Aluminum (2) Bronze 8 ft (1) 6 ft 2.5 ft- *-1.5 ft- A B C Aluminum (3) 3 ft D P
Rigid bar ABC is supported by bronze rod and aluminum rod as shown in the figure. A concentrated load
P is applied to the free end of aluminum rod (3). Bronze rod has an elastic modulus of 15,000ksi and a diameter
of 0.65in. Aluminum rod (2) has an elastic modulus of 10,000ksi and a diameter of 0.85in. Aluminum rod (3) has
a diameter of 1.20in. The yield strength of the bronze is 52ksi, and the yield strength of the aluminum is 42ksi.
a. Determine the magnitude of load P that can safely be applied to the structure if a minimum factor of
safety of 1.70 is required.
b. Determine the deflection of point D for the load determined in question (a).
c. The pin used at B has an ultimate shear strength of 56ksi. If a factor of safety of 3.0 is required for
this double shear pin connection, determine the minimum pin diameter that can be used at B.
