Question

Pins B and C experience the same force, and are both used in a double shear connection. Consider pin B. Use the ultimate shear strength, the factor of safety, and the force at B to calculate the minimum required diameter for pins B and C. dpin B,C= ? (unit mm)

Rigid beam AB is subjected to a distributed load that increases linearly from zero to a maximum intensity of wB = 24.5 kN/m. Beam AB
is supported by a single-shear pin connection at joint A and by a double-shear connection to member (1) at joint B. Member (1) is
connected to the support at C with a double-shear pin connection. Use dimensions of a = 2.3 m, b 0.9 m, and c = 1 m.
(a) The yield strength of member (1) is 309 MPa. A factor of safety of 1.7 with respect to the yield strength is required for the normal
stress of member (1). Determine the minimum cross-sectional area required for member (1).
(b) The ultimate shear strength of the material used for pins A, B, and Cis 210 MPa. A factor of safety of 2.8 with respect to the
ultimate shear strength is required for the pins, and all three pins are to have the same diameter. Determine the minimum pin
diameter that may be used.
