1. The tongs are used to grip the ends of the drilling pipe with the center at C. a) At what angle 0 would the torque (moment) reach a maximum about C? b) What is the value of that maximum 36.87e A F=500 Ibs torque or moment (using the angle in (a) ) about C? c) If the slope of the force was set to a 3/4 slope (i.e., y=3 and x=4) what would the torque or moment be about point C? d) Check your answer in (c) above by calculating the moment of this force about C by using a Vector 10.0 in Mp formulation with the position vector 30.0 in CD. (Show the matrix and then DC = 31.62 calculate it manually and use your calculator to verify the manual calculation.)

A 3.0-m rod is pivoted about its left end. A force of 6.0 N is applied perpendicular to the rod at a distance of 1.2 m from the pivot causing a ccw torque, and a force of 5.2 N is applied at the end of the rod 3.0 m from the pivot. The 5.2 N is at an angle of 25 degrees to the rod and causes a cw torque. What is the net torque about the pivot? Choose – 6.3 Nm –1.7 Nm 0.6 Nm – 0.6 Nm
Consider an unsuccessful attempt to take off a tire using a wrench to loosen the bolts. Assume the wrench is 0.3m long and are you able to apply a 200N force Because the tire is flat you can only apply your force at a 60° angle. What is the torque at the center of the bolt. You find a tire jack and are now able to apply 200N of force at an 80° angle. Is the resulting torque more or less and what is the new torque.
