###### Question details

Beam *AB* is supported as shown in the figure. Tie rod
(1) is attached at *B* and *C* with double shear pin
connections, while the pin at *A* is attached with a single
shear connection. The pins at *A*, *B*, and
*C* each have an ultimate shear strength of 51 ksi, and tie
rod (1) has a yield strength of 38 ksi. A concentrated load of
*P* = 13 kips is applied to the beam as shown. A factor of
safety of 2.7 is required for all components. Assume *c* =
8.2 ft, *d* = 11 in, *a* = 3.5 ft, and *b* =
7.8 ft. Determine:

(a) the minimum required diameter for tie rod (1).

(b) the minimum required diameter for the double shear pins at
*B* and *C*.

(c) the minimum required diameter for the single shear pin at
*A*.
