Question
Situation 1: A rigid bar ABC weighs 10 kN/m. The compressive stress of the copper bar is 20 MPa. Answer the following questions:
3m
B
2 m
Copper
L=3m
A = 1500 mm²
Brass
C
L = 2 m
A = 1200 mm²
A. What is the stress of the brass bar? Indicate if
it will experience tension (T) or compression
(C) (MPa)
B. What is the minimum required diameter of the
pin at A assuming that the pin connection is
in double shear? Consider the allowable
shearing stress of the pin as 15 MPa. Round
your answer in a multiple of 5. (mm)
