Example 8.6 A Weighted Forearm Goal Apply the equilibrium conditions to the human body. -Humerus Problem A W = 47.3 N (11 lb) weight is held in a person's hand with the forearm horizontal, as in Figure 8.11. The biceps muscle is attached d = 0.0302 m from the joint, and the weight is / = 0.351 m from the joint. Find the upward force F exerted by the biceps on the forearm (the ulna) and the downward force R exerted by the humerus on the forearm, acting at the joint. Neglect the weight of the forearm. W Biceps Ulna W (a) (b) Figure 8.11 (a) A weight held with the forearm horizontal. (b) The mechanical model for the system. Strategy The forces acting on the forearm are equivalent to those acting on a bar of length 0.351 m, as shown in Figure 8.1lb. Choose the usual x- and y-coordinates as shown and the axis O on the left end. (This completes Steps 1 and 2.) Use the conditions of equilibrium to generate equations for the unknowns, and solve. Solution ET; = TR + TF + TBB = 0 R(0) + F(0.0302…
6. Two close-coiled helical springs are arranged, parallel (one inside the other) about the same longitudinal axis. Both springs have the same number of coils and same overall length, but the mean coil diameter of the outer spring, which is made of steel wire, is twice that of the inner spring, which is made of bronze wire. The springs are designed to act together when a tensile force is applied, so that both suffer the same change in length and each carries half the force. Determine the ratio of the wire diameters, and the retio of the stresses produced in the wires, if Esteel = 2 x Ebronze

4.3. Assessing Risk of Aneurysm Rupture: Studies suggest that the maximum allowable stress (failure strength) for the wall tissue in an aortic aneurysm is o = 220 kPa, after accounting for factor of safety. A physician wants your expert opinion on the maximum diameter that an aortic aneurysm in a hypertensive patient (BP 200/90 mmHg) could be allowed to grow to before rupture becomes imminent. The wall thickness may be assumed to remain unchanged at t = 1.2 mm. State your answer in millimeters of diameter. INDBER

In Chapter 11 we are much smarter and are able to show that for a cantilever beam, the force required to deflect the end, as is illustrated in Figure 4.32 is F= Fig. 4.32 Cantilever beam subjected to a force at the end. 3EI -X, where E is the modulus of elasticity, which is a property of the material used, I is the area moment of inertia of the cross-section of the beam, and L is the length. If a mass m,is attached to the end of the beam, what is the equation of motion for the vertical motion of the beam? If the length is doubled, what is the change in frequency of the free vibration of the beam? x=0 F x=L
