5/33 MCQs for:
MECHANICS : FORCES - Moments
The moment of a force is defined as:
The distance between the point of application of the force and the pivot.
The weight of the object.
The turning effect of a force.
The force applied to a point.
What is the unit of moment (torque)?
Watt (W).
Newton-meter (N·m).
Joule (J).
Newton (N).
In an experiment where weights are placed on a beam, the moment is calculated as the product of:
The mass and the height of the beam.
The force and the angle of application.
The weight and the length of the beam.
The force and the perpendicular distance from the pivot.
Which of the following is NOT a condition for static equilibrium?
The sum of forces in the x-direction is zero.
The sum of forces in the y-direction is zero.
The object is moving at constant velocity.
The sum of moments about any point is zero.
In the case of a co-planar pair of parallel forces, which condition must be satisfied for equilibrium?
The forces must be balanced in magnitude.
The forces must act in opposite directions.
The moments about any point must be zero.
The sum of the forces must be zero.
