Answer:
4.9N approx.
Explanation:
Step one:
given data
length of rod r= 2.25m
Required torque = 11 Nm
Required
The force needed to produce a torque of 11Nm
Step two:
"By definition, Torque is the twisting force that tends to cause rotation.
The point where the object rotates is known as the axis of rotation."
Mathematically,
[tex]\tau = rF\sin\theta[/tex]
[tex]\tau[/tex] = torque
r = radius
F = force
[tex]\theta[/tex] = angle between F and the lever arm
in this case is zero
[tex]\tau = rF\\\\F=\tau/r[/tex]
substituting we have
F=11/2.25
F=4.88N
F=4.9N approx.
