A 0.7-lb block rests on top of a 0.5-lb block supported by but not attached to a spring of constant 9 lb/ft. The upper block is suddenly removed. Determine (a) the Maximum velocity reached by the 0.5-lb block, (b) the maximum height reached by the 0.5-lb block.
It is known that the kinetics of recrystallization for some alloy obey the Avrami equation, and that the value of n in the exponential is 8.4. If, at some temperature, the fraction of recrystallization is .30 after 100 min, determine the rate of r..

A satellite changes its orbit inclined 66 degrees at 260.0 km altitude to a polar orbit at the same altitude. What Delta V was required?
If the filling is done rapidly, calculate the final temperature in the small cylinder, (a) assume that oxygen is an ideal gas with Cv= 5R/2 and (b) using accurate thermodynamic data for oxygen.
Problem Statement Consider the landing gear shown below. Working in teprns of two, come up with a single optimized design for given operational conditions and design considerations
The system is at rest in the position shown, with the 12-lb collar A resting on the spring (k = 20 lb/ft), when a constant 30-lb force is applied to the cable. What is the velocity of the collar when it has risen 1 ft? The collar is attached to th..
