PROBLEM SOLVING:
1. A square steel tube below is used to sustain a compression load of 480 KN. If the steel square tube have a
compressive strength of 180 MPa and a side of 100mm, determine the thickness of the tube.
The rigid bar ABC is supported by a pin at A and a steel rod at B. Determine the largest vertical load P that
can be applied at C if the stress in the steel rod is limited to 35 ksi and the vertical movement of end C must
not exceed 0.12 in. Neglect the weights of the members.
3. The rigid bars AB and CD are supported by pins at A and D. The vertical rods are made of aluminum and
bronze. Determine the vertical displacement of the point where the force P = 10 kips is applied. Neglect the
weights of the members.
4. Two 1.75-in-thick rubber pads are bonded to three steel plates to form the shear mount show in the figure.
Find the displacement of the middle plate when 1200-lb load is applied. Consider the deformation of rubber
only. Use E = 600 psi and v= 0.45 for rubber.
5. A uniform bar of length L, cross-sectional area A, and a unit mass p is suspended vertically from one end.
Derive the formula for its elongation considering its own weight ONLY. Show the unit of every variable.
