Question

Transcribed Image Text:In our first example, we will see that we can use a
lever arm to greatly increase the torque without having
to provide more force. Suppose, for instance, that an
amateur plumber, unable to loosen a pipe fitting, slips
a plece of scrap pipe (sometimes called a "cheater")
over the handle of his wrench, He then applies his full
weight of 900 N to the end of the cheater by standing
on it. The distance from the center of the fitting to the
point where the weight acts is 0.80 m, and the wrench
handle and cheater make an angle of 19° with the
horizontal (Figure 1). Find the magnitude and direction

Transcribed Image Text:If the pipe fitting under consideration can withstand a maximum torque of 650 N- m without
breaking, what is the smallest angle at which our amateur plumber can safely stand on the end of the
cheater and apply his full weight without breaking the pipe fitting?
Express your answer in degrees.
