When solving a torque problem, all lever arms are measured from the ...
end of the bar
pivot or fulcrum
center of the bar
center of the mass
As shown above, a rod with a length L is free to rotate about point A. An external force F is applied perpendicular to the rod. In which of the following cases is the torque on the rod the same as the above?
A state of equilibrium is also seen in the diagram. Each of the cars weighs the same 9800 N. Despite the fact that there is only one car on the left-hand side that is 9 m from the fulcrum, the torques balance because, the cars on the right-hand side, are ____meters from the fulcrum.
4.5 m
3 m
1 m
2 m
When an object is experiencing a net torque?

Concurrent forces
Center of gravity
Rigid body
Conditions for equilibrium are:
1st condition: net force = 0
2nd condition:net torque = 0
Moving with constant velocity or Stationary/ rest
True
False
The study of forces in equilibrium is called
statics
dynamics
equilibriation
kinematics
In the diagram, two masses, one with mass m, the other with mass M = 2m are resting on a uniform plank of length L that pivots at its midpoint. If the mass m is at the far end of the plank, how far away from the pivot should the mass M be to balance the plank in a horizontal position shown?
L/2
L/3
L/4
L/6
A disk initially rotating counterclockwise (CCW) at a certain constant angular speed is suddenly being pulled on by two strings T1 and T2, where T2 > T1. What is going to happen next?
The disk will continued rotating CCW at the constant angular speed.
The disk will continued rotating CCW but it will speed up
The disk will slow down and start rotating CW
The disk will eventually stop rotating
In what direction is torque considered negative?
clockwise
counter clockwise

What is the effect of putting a fulcrum in a particular place? Click both correct answers
it removes the force from the problem
it acts as a new support
It reduces the length of the lever arms
it gets rid of the mass of the object
