Question

Apply the second condition for equilibrium (Step 3) and solve for the upward force F: Sigmar_i=r_R+r_F+r_BB=0 R(0)+F(0.0300m)-(50.0N)(0.350m)=0 Apply the first condition fen equilibrium (Step 4) and solve (Step 5) for the downward force R: SigmaF_3=F-R-50.0N=0 R=F-50.0N=583N-50 N= The magnitude of the force supplied by the Weeps must be about ten times as large as the bowling^supporting! Suppose the biceps were surgically reattached three centimeters farther toward the person's hand. If the same bowling ball were again held in the person's hand, how would the force required of the biceps be affected? Explain. Suppose you wanted to limit the force acting on your joint to a maximum value of 8.00 times 10^2N. (a I these circumstances, what maximum weight would you attempt to lift? (b) What force would your biceps applying this weight?

Explanation / Answer

Placing the pivot point at the bicepts

by balancing torques

(800)(0.350) = (F)(0.350- 0.030)

Fy = 875 N

for vertical equilibrium

Fy = x + 800 N

875 N = x+ 800 N

x = 75 N
