Appreciate if someone can check my answers to the following question:

A beam hinged at one end and simply supported at the other is subjected to the loading shown. A design calculation is required to determine the suitable size of hinge pin. If wrong, could you point me in the right direction.

Data Shear strength of pin material = 20 MN/m^2

Factor of safety = 5

Drawing of system can be found here:

a) Use these conditions to determine the reaction forces RP and R1

b) State the maximum working shear stress in the pin.

c) Calculate a suitable diameter for the pin to the nearest millimeter.

a) My answers are RP = 1700 N, and R1 = 800 N.

b) My answer 4 MN/m^2

c) My answer = 16 mm
