Forces and Motion – Collisions

A collision occurs when an object hits another object. A collision can occur between two objects in motion, or by an object in motion and an object at rest. During a collision, kinetic energy is transferred between the colliding objects. A collision occurs when a tennis player hits a tennis ball. Kinetic energy is transferred from the player’s moving tennis racket to the ball, causing it to move. The more kinetic energy that is transferred, the faster and farther the tennis ball will move. During a collision, the faster an object is moving, the greater the energy transfer and the greater the impact on the other object. We can see this by looking at car accidents. If the cars are traveling slowly at the time they collide, there may be little damage to the cars. If the cars are traveling faster, there is a much more observable impact. There is likely to be more damage to the cars. The observable impact of a collision reflects how much energy was transferred between objects and relates to the amount of energy of the moving object. At the start of a game of billiards, a player uses a large force to hit one ball into the other balls. The ball gains kinetic energy from the billiard cue and moves down the table. As it hits the other balls, a loud sound is made. Kinetic energy is transferred to the other balls as they scatter all over the table. When a player uses a smaller force, less kinetic energy is transferred. The balls produce a softer sound when they collide and move more slowly. Motion is the process of changing position. When something is moving it is in motion. An object that is in motion has kinetic energy. We can describe motion by measuring its speed and direction. Speed is the time it takes an object to cover a certain distance. The faster an object covers a distance, the greater its speed. Direction is which way an object is moving. The greater the speed of an object, the more energy it has. Forces can also affect the motion and energy of an object. Larger forces will cause objects to move faster and have more energy than smaller forces. All forms of energy can be described as either stored energy or moving energy. The stored energy in an object is called potential energy. Food has potential energy. The energy is transformed into other forms when we eat the food and use the energy to move about, keep warm and stay healthy. Potential energy is also related to the shape and position of an object. If you hold a ball above your head, the ball has potential energy due to its position. If you drop the ball, the potential energy is transformed into moving energy. When potential energy is released, it is converted into kinetic energy. Kinetic energy is the energy of an object due to its movement. All moving objects, from the tiny particles that make up our air to an airplane flying in the sky, have kinetic energy. The amount of kinetic energy in an object depends on how fast it is moving. The faster an object moves, the greater its kinetic energy.

How Semitrucks Are Crash Tested | Carsplainers | Insider Cars

Just like consumer cars have to undergo crash testing, so do commercial semitrucks. While some of these tests are the same that production cars undergo, others are designed specifically for trucks. Thanks to trucking companies like Volvo and Scania as well as the Insurance Institute for Highway Safety, safety standards for these trucks are only improving. Correction: In the video, we said that the trucks weighed 120 tons. The trucks are 8 to 12 tons and crashed at speeds of 30 to 50 miles per hour. We regret the error. Thank you.

Tips for Winter Truck Driving

Driving a truck in the winter can be a challenge even for the most experienced drivers. There are many precautions that drivers should take while driving in winter weather conditions.

Truck drivers should always listen to their CB while driving in winter conditions. Many other drivers will be able to tip off other drivers when the weather conditions worsen ahead. Also many companies offer weather updates at least once per day. It is very important to pay attention to the weather advisory while driving in winter conditions.

Another useful tip that experienced drivers offer is to take all ramps at least 5 miles per hour less than the posted signs. The posted limits on ramps are designed for standard conditions in automobiles. Anytime trucks are traveling in bad weather it is better be safe than sorry.

A good indicator of icy roads it to keep an eye on the back of the side view mirrors. When ice starts to build up on the back of the side view mirror it will most likely also be on the road ahead.
Always pay attention to oncoming traffic. If traffic heading in the direction that the driver is going has slowed down, or there is a minimal amount of trucks in oncoming traffic, it is a good indicator that weather conditions ahead have worsened.

Most importantly, drivers should always drive only in their comfort zone. The safety of a driver and the other drivers on the road is always more important than any load that needs to meet its destination. Anytime conditions worsen to a point that the driver is out of their comfort zone or skill level it is advised to shut down and resume driving only after conditions have improved.

Inspecting and Maintaining Tires Will Minimize Roadside Service Calls

It is well documented that the No. 1 cause of roadside service calls is tires. No wonder, there are 18 tires on a typical line-haul service vehicle, more tires than any other vehicle component. You can have the best vehicle maintenance program on the planet, but once that truck leaves the terminal, a number of tire issues can occur that can lead to a roadside service call.

Tread area punctures are the top cause of air loss. A tire failure depends on the size of the puncturing object, in combination with the specific penetration location. If that nail penetrates through one of the tread grooves, chances are higher the nail will break through the tire casing, causing air loss. Tires do not normally have a sudden air loss when a vehicle picks up a puncturing object; they lose air slowly. It may take a few days to lose enough air pressure where the tire sidewalls begin excessive flexing, which generates additional heat build-up.

The tire footprint becomes longer as the tire pressure is reduced, meaning more rubber on the road—which also leads to increased heat. Heat is a tire’s worst nightmare. When a tire continues to generate excessive heat, the rubber actually begins to chemically break down, which will lead to a tire failure. The fact that someone just checked all 18 tires at the morning vehicle walk-around has no bearing on picking a up a nail five minutes down the road.

Sidewall damage/snags are another cause of tire failure. Right side or curb side trailer tires are especially prone to sidewall issues. Vehicles that turn frequently in city driving have the highest incidence of tire sidewall damage. Driver education can play a major role in reducing trailer tire sidewall damage. Drivers who have been on the road for many years will have fewer trailer tire sidewall damage issues than a new driver.

When a vehicle is pulled over for a roadside inspection, tires are high up on the inspector’s checklist. Inspectors are looking for tires with tread depth below the minimum 4/32-in. for steers and 2/32-in. for drives, trailers and dollies. They also are looking for exposed belts and/or fabric along with flat tires. By definition, a tire is flat when the measured air pressure is 50% or less of the maximum tire pressure molded onto the tire sidewall.

If any of these tire conditions are present, the vehicle is flagged as being “out-of-service.” A roadside service call is the only solution for getting the truck up and running again.

There is no excuse for a fleet to have an inspector flag its vehicle as being out-of-service because of a tire-related issue. These types of tire conditions should have been caught during the daily vehicle walk-around. Drivers must be trained to visually inspect tires, take tread depths and even measure tire pressure. It sounds like it is routine, but it’s not. Working with your tire professional on a tires 101 training class will go a long way to reduce roadside service calls.

Visual tire inspections should include running a hand over the tread and sidewall to look for signs of irregular wear and punctures. If a tire is getting close to the legal tread depth, a tread depth gauge measurement is strongly suggested. Make sure to check that the tread depth gauge measures 0 on a flat. Don’t take a measurement at a treadwear indicator location or on top of one of those stone ejectors located at the bottom of many grooves. If you do, you could be off 2/32-in. or 3/32-in.

Measuring tire pressure using a calibrated pressure gauge is very critical. Air carries the load, and tires with low air pressure will lead to excessive heat and premature tire removals. Tire gauges are simple devices, but will quickly lose accuracy. Even a new stick gauge is only accurate to +/-3 PSI brand new, out of the box.

A serious tire program, which includes comprehensive driver training regarding tires, will go a long way in reducing-tire related roadside service calls.
