Use the figure to answer the following questions. A magnet of mass 5.58 kg is suspended from the ceiling by a cord as shown. A large magnet is somewhere off to the right, pulling on the small hanging magnet with a constant force of F = 152.5 N. At what angle theta ?with respect to the vertical does the magnet hang? a. 70.3 degrees b. 19.7 degrees c. 54.0 degrees d. 59.0 degrees Consider the same situation as in the previous problem. This time the magnet has mass 6.70 kg and the force pulling the magnet to the right has magnitude 99.9 N. What is the magnitude of the tension force in the cord? a. 199.6 N b. 292.2 N c. 119.6 N d. 165.6 N

Two blocks are connected by a (massless) string that passes over a (massless, frictionless) pulley as shown: What is the tension in the string? Express your answer in N.
A mechanic is reinstalling a newly-sharpened blade on a lawn mower. A wedged-in block of wood at C prevents the blade from rotating as the 33-lb force is applied to the wrench handle. The blade is bolted to a bracket attached to the motor shaft O, which protrudes through the bracket and blade. Determine the normal force at C. State any assumptions. Does it matter whether the bolt at Bis installed? 5.1" 33 lb Answer: NC-1 2.02.0 COB

Replace the three forces shown by an equivalent force-couple system at point A. If the forces are replaced by a single resultant force, determine the distance d below point A to its line of action. 230 N 420 mm 420 mm 130 N 420 mm 270 N Answers: Force-couple system at A. The force is positive if to the right, and the couple is positive if counterclockwise. R = i N M = i N-m Single resultant force. d = i mm
