###### Question details

Calculate the reduced nominal design strength (phiPn) of a 1 ¼” diameter-A36 threaded steel rod. Determine if the serviceability limit states are satisfied if the length of the member is 18 ft.

Assume: Service load deflection limit is ½” (i.e. Deflection ≤ ½”) Service load = 0.75 x phiPn
