What is kinetic energy?
Expert Solution & Answer
To determine
What kinetic energy is?
Explanation of Solution
Kinetic energy is a form of mechanical energy possessed by a body in motion. The amount of kinetic energy is determined by the mass and speed of the body. The higher the mass and speed, the higher is the kinetic energy. Even at low speeds, the vehicle with high mass has enough kinetic energy to cause serious injury and damage. The kinetic energy is disposed with the help of brake system in a safe and controlled manner.

- A viscoelastic column is made of a material with a creep compliance of D(t)= 0.75+0.5log10t+0.18(log10t)^2 GPA^-1 for t in s. If a constant compressive stress of σ0 = –100 MPa is applied at t = 0, how long will it take (= t1/2) for the height of the column to decrease to ½ its original value? Note: You will obtain multiple answers for this problem!

The emissivity of the transistor and the plate surfaces is 0.9. Assuming the heat transfer from the back side of the plate to be negligible and the temperature of the surrounding surfaces to be the same as the air temperature of the room, determine the length of the square plate if the average surface temperature of the plate is not to exceed 50°C. Start the iteration process with an initial guess of the size of the plate as 43 cm. The properties of air at 1 atm and the film temperature of (Ts + T)/2 = (50 + 30)/2 = 40°C are k = 0.02662 W/m·°C, ν = 1.702 × 10–5 m2 /s, Pr = 0.7255, and β = 0.003195 K–1.
