design conditions:
(a) The pin at point R, enlarged in Figure 2, is 10.0 mm diameter. What load can be supported
by the pin if the ultimate shear strength of the pin is 195 MPa and a safety factor of 2.0 based
on ultimate strength is required?
(b) Using the load condition from (a), size cable ST if it has a design stress of 207.5 MPa.

A structural support for a machine is subjected to a static compression load of 20 kN. The support is
manufactured from a circular rod made from SAE 1040 Hot Rolled steel. Specify suitable diameter for the
cross section of the rod based on the basic size. Steel data are available in Table A-10 from the textbook.
Using the results of problem 2, plot the shear force as a function of the shaft diameter using an Excel sheet. (5 mm (< or= to) D (< or= to) 100 mm)
