Aspring with a spring constant k of 100 pounds per foot is loaded with 1-pound weight and brought to equilibrium. it is then stretched an additional 1 inch and released. find the equation of motion, the amplitude, and the period. neglect friction. then

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.

When you hold a rectangular object, how does the area of the side that is resting on your hand affect the pressure and the force that the object exerts?
