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 32-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? 5.9" 32 lb Answer: Ne 2.02.0 AO OB 7.3 lb
