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 23-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 B is installed? 6.5" 23 lb Answer: Nc= i 2.02.0" AOOOB -6.9" C lb
