Unformatted text preview: m that the frame will safely support Answer m = 2421 kg Problem 23 (Problem 6.80 from Bedford et al). The weight W = 60 kip. What is the magnitude of the force the members exert on each other at D . Answer | ~ D | = 110 kip 2 Problem 24 (Problem 6.81 from Bedford et al). The gure is a diagram of the bones and biceps muscle of a persons arm supporting a mass. Tension in the biceps muscle holds the forearm in horizontal position as illustrated in the simple me-chanical model as shown in Fig b. The weight of the forearm is 9N and the mass m = 2 kg 1. Determine the tension in the biceps muscle AB 2. Determine the magnitude of the force exerted on the up-per arm by the forearm at the elbow joint C . Answer T AB = 166 . 76 N F C = 138 . 65 N Problem 25 (Problem 6.89 from Bedford et al). Determine the force exerted on the bold by the bolt cutters. Answer F = 1051 N 3...
