1. Consider a loaded mine cart weighing 3000 lb with 1500 Ib of high-grade ore from an
underground mine. Compute the equivalent stiffness and the equivalent static deflection in the
wire rope without load and with load. Also, draw the free body diagram of the mechanical
system. Let the values of modulus of elasticity and modulus of rigidity to be 30 x 106 psi and
11.6 x 10° psi respectively. (30pts.)

Suppose a 1.6-oz golf ball is placed on a vertical spring with force constant k = 2 lb/in. The spring is compressed 6 in. and released. About how high does the ball go (measured from the spring’s rest position)?
2- A constant force of (2kN) pulls a box along a level floor a distance of (10 m) in (50 s). What is the power used?
A spring has a natural length of 10 feet, and when an 64lb weight is attached, the spring measures 13.2 feet. The weight is initially displaced 4 feet above equilibrium and given a downward velocity of 3 ft/sec. Find its displacement for t>0 if the medium resists the motion with a force of two Ibs for each ft/sec of velocity.

5. A 15 foot chain hangs from a winch 15 feet above ground level. A bucket of water lies attached to the other end of the chain. The winch begins to wind up the chain. Once the bucket leaves the ground it begins to leak water at a constant rate. Assume that the water bucket weighs 20pounds in the beginning and only 5 pounds once it reaches the winch. Also assume that the chain has a linear density of 3 pounds per foot. Find the work done by the winch during this process.
How stress and strain distribute in an elastic body when load is applied on its cross sectional area.
The 0.50 lb ball is shot from the spring device shown. The spring has a stiffness k = 10 lb/in. and the four cords C and plate P keep the spring compressed 2 in. when no load is on the plate. The plate is pushed back 3 in. from its initial position. (Eigure 1) If it is then released from rest, determine the speed of the ball when it travels 23 in. up the smooth plane. Express your answer to three significant figure and include the appropriate units. HA Value ft/s v = 30
A spring has a natural length of 20.0 cm. If a 21.0-N force is required to keep it stretched to a length of 30.0 cm, how much work W is required to stretch it from 20.0 cm to 25.0 cm? (Round your answer to three decimal places.) W = A particle is moved along the x-axis by a forct. Atat measures 4/(3 + x)2 pounds at a point x feet from the origin. Find the work w done in moving the particle from the origin to a distance of 9 t. ft-lb Need Help? Watch It Master it
