STRENGTH OF MATERIALS

An aluminum alloy [E = 8900 ksi] pipe with a cross-sectional area of A1 = 4.57 in.2 is connected at flange Bto a steel [E = 26600 ksi] pipe with a cross-sectional area of A2 = 3.08 in.2. The assembly is connected to rigid supports at Aand C. Assume L1=168 in., L2=228 in., and P=52 kips. For the loading shown, determine:(a) the normal stresses in aluminum pipe (1) and steel pipe (2) (,  use positive if tensile, negative if compressive).(b) the deflection uB (use positive if it moves to the right and negative if it moves to the left) of flange B.

CALCULATE THE FORCE IN THE CABLE C AND D, AND EXTENSION IN CABLE D.

5) Refer to the figure: C: E 10,000 ksi D: E 30,000 ksi L 12.0 in A 0.1 in L = 15.0 in A 0.2 in Forces in wires C and D Movement of Point D Required: (20 point bonus) Rigid Link 18 5000 lbs.

Steps to solve:

  1. Draw FBD
  2. Taking moment about A
  3. Use triangle properties and find relation.
  4. Now find force in member C and D.
  5. finally calculate the movement of D using Axial deflection formula.
