Answer #1

Here, given data is:

theta = 30 degree

r = 35 cm = 0.35 m

Torque , T = - 11 N.m

Let the force applied by Luis is F.

The expression for torque is,

T = r * F * cos(theta)

11 = 0.35 * F * cos(30)

F = 36.2905 N

Therefore, the force that must be applied by Luis is 36.2905 N.

    Spark plugs should be tightened to a specified torque of 9.45Nm. You have a wrench that is 0.27 m long, but because of the tightness of the space you can't pull the wrench at a ninety degree angle. You must pull at an angle of 38.12 degrees, measured from the handle of the wrench. What force must you exert on the wrench?
