Question

A torsion spring of a mousetrap is twisted
through an angle of 180°. The torque vs.
angle data is given below.
Torsion, T(N- 1
m)
10
20
30
40
Angle, e(rad) 10
100 400 600 1200
The relationship between the torque and the
angle is T = ao + a 0. The correct
regression model that represents the data is:
O T= 29.684 0 - 139.43
T= 22.782 0 +1
None
T = 30 0 - 200
T = 60 0 – 1200
T = 0.095086 e + 0.11868

A wrench is used to apply a torque to a bolt. Forces F1 through F6 all have the same magnitude. The point of application of force F1 (and F4) is a distance d from the center of rotation of the bolt. The application points of F1, F2, and F3 are all distance d apart, as shown. Use the convention that counter-clockwise torques are positive; clockwise torques are negative. Determine the torque applied on the bolt by F6 in terms of the variables and angles given in the problem.
