Let us represent
the net torque is calculated accordingto the equation
so the net torque exerted on the drum will be
if we take that the cable does not slip then we can write
in the above equation
T is the counter clockwise torque providedby the motor and a is the acceleration of the cord as from the given we can see that
in the next step we take
apply newtons second law oftranslational motion to the crate then we get
now solving for
= ....... N.m
The figure shows the surface created when the cylinder
The figure is something like:
A marble moves along the x-axis. The potential-energy functionis shown in Fig. 1
a) At which of the labeled x-coordinates is the force on the marble zero?
b) Which of the labeled x-coordinates is a position of stable equilibrium?
c) Which of the labeled x-coordinates is a position of unstable equilibrium?
