Question
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
36.87€$k1
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
y 3
point C?
d) Check your answer in (c) above by
calculating the moment of this force
about C by using a Vector
formulation with the position vector
CD. (Show the matrix and then
calculate it manually and use your calculator to verify the manual calculation.)
