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.)
