A two-tier system to repair bridges is supported by two steel cables for each platform. Lengths of the cables are la = 50 in. and lp = 190 in. Assume that two 190 lb workers are going to be standing on the system to repair a bridge, one on each platform. The following design requirement must be met: the stretch of each cable must be less than 0.02 in. at the worst-case loading condition for each cable. 140 in. 250 lb 190 in. 400 lb Determine the minimum diameter required for each cable. (Express your answers using two decimal places.) Cable at A: in. Cable at B: in. Cable at C: in. Cable at D: in.
