Relative density

We start our discussion with a brief review of the concepts of stress and strain. Recall that stress is a force acting on a material that produces a strain. Stress is a force applied over an area and therefore has units of Force/area (like lb/in 2). Pressure is a stress where the forces act equally from all directions.

The impact force can be calculated as. F max = 1/2 (2000 kg) (16.7 m/s) 2 / (0.5 m) = 558 kN. Note that the gravitation force (weight) acting on the car is only. F w = m g = (2000 kg) (9.81 m/s 2) = 19.6 kN. The impact creates a force 28 times gravity!! A person sitting inside the car with seat belts on will de-accelerate with a force 28 times ...

Analysis of standing vertical jumps using a force platform

Weight is a downward force (gravity acting on mass); buoyancy is an upward force. If these two forces are balanced, then so-called neutral buoyancy (object hovers) is achieved. If they are not balanced, the object immersed will either sink (weight greater than upward buoyant force) or float (weight less than upward buoyant force).

If I submerge anything, the net force acting upwards on it, or the amount that I'm lighter by, is equal to the weight of the water being displaced. That's actually called Archimedes' principle. That net upward force due to the fact that there's more pressure on the bottom than there is on the top, that's called the buoyant force.
