Q1. (10 Marks) The solid 30 mm diameter bent rod AB is connected to a frictionless vertical square rod using a collar at A and is supported by a cable BC. The rod material has a mass density of 7850 kg/m and is loaded at D as shown in the figure. Using cartesian vector methods and neglecting the size and weight of the collar; a) Determine the tension in the cable BC and the components of reactions acting on the collar at A necessary to hold the rod in equilibrium. b) If 6 mm diameter wire rope with a maximum load capacity of 6 kN is used for the cable BC, what is the factor of safety based on load? 2.5 m 3.5 m 600 N 200 N D x 1 m B Q2. (10 Marks) For the assembly shown, a 10-mm-diameter pin is used at A, and 12-mm-diameter pins are used at B and D. Knowing that the ultimate shearing stress is 110 MPa for all pins and that the ultimate normal stress is 225 MPa for link BD, determine the maximum allowable load P if an overall factor of safety of 3.25 is desired.
