Torque and Chrome

please help me pass please include how you got the answer?

A plumber uses a torque wrench to loosen a corroded nut. A) if he exerts a force of 400 N perpendicular to the wrench handle and the wrench is 15 cm long, then how much torque does the wrench experience? B) If he exerts a Force of 400N at an angle of 40° from the perpendicular on the same wrench, then how much torque does the wrench experience? C) what might a plumber have available to help generate more torque easily?

1. plumber uses a torque wrench to loosen a corroded nut. Torque = Force * distance * sine of angle A) if he exerts a force of 400 N perpendicular to the wrench handle and the wrench is 15 cm long, then how much torque does the wrench experience? Torque = Force * distance * sine of angle Torque = 400 * 0.15m * sin 90° Torque = 60 N-m B) If he exerts a Force of 400N at an angle of 40° from the perpendicular on the same wrench, then how much torque does the wrench experience? Torque = Force * distance * sine of angle Torque = 400 * 0.15m * sin 490° Torque = 38.6 N-m C) what might a plumber have available to help generate more torque easily? I have a pipe wrench with a 3 ft handle. 3 ft = 36 in * 2.54 cm/in = 91.44 cm = 0.9144m A wrench with a longer handle 60 N-m = F * 0.9144 m F = 97.66 N which is approximately ¼ the original 400 N I also have a 8 ft long pipe that I slip over my 3 ft pipe wrench We call this pipe a cheater bar 8 ft = 2.44 m 60 N-m = F * 2.44 m F = 24 N which is approximately 1/16 the original force A toddler could remove the corroded nut!!
