Question 5
The lug nut on the wheel of the automobile is to be removed using the wrench and applying
the vertical force of F = 30N at A as shown in the image below.
F= 30 N
0.25 m
0.3 m
a)
Detemine if this force is adequate, provided 14 N.m of torque about thex axis is initially
i.
required to tum the nut.
Ifthe 30N force can be applied at 4 in any other direction, will it be possible to tum the
i.
nut?
b) Ifthe extension pipe AB is slipped over the handle of the wrench and the 30-N force can
be applied at any point and in any direction on the assembly.
