Transcript text: 15 Which of these statements describes a moment?
A The pushing effect of a force
B The pulling effect of a force
C The turning effect of a force
D The compressing effect of a force
Solution
Solution Steps
Step 1: Understanding the Concept of a Moment
A moment in physics refers to the turning effect produced by a force acting at a distance from a pivot point. It is calculated as the product of the force and the perpendicular distance from the pivot to the line of action of the force.
Step 2: Analyzing Each Option
Option A: The pushing effect of a force describes a linear force, not a moment.
Option B: The pulling effect of a force also describes a linear force, not a moment.
Option C: The turning effect of a force accurately describes a moment.
Option D: The compressing effect of a force describes a force causing compression, not a moment.
