Question 25

A camera support arm is horizontal and can turn in a vertical plane about a pivot at its centre. A cable pulls upwards with a force of 5.0 N at a point 40 cm to the right of the pivot. A second cable pulls downwards with a force of 15 N at a point 20 cm to the left of the pivot. What is the resultant moment acting on the support arm?
