Answer :
Final answer:
To find the resistance force when the effort force is given at a certain distance, we can use the principle of moments. Using the equation (Effort force) x (Effort distance) = (Resistance force) x (Resistance distance), we can solve for the resistance force. In this case, the resistance force is approximately 271.4 N.
Explanation:
To find the resistance force when the effort force is 176 N at 76.3 cm, we can use the principle of moments, which states that the sum of the clockwise moments is equal to the sum of the anticlockwise moments. The moment is the product of the force and the distance from the pivot. In this case, we can set up the equation as follows:
(Effort force) x (Effort distance) = (Resistance force) x (Resistance distance)
Substituting the given values, we get:
(176 N) x (76.3 cm) = (Resistance force) x (49.2 cm)
Solving for the resistance force, we find that it is approximately 271.4 N.
