Question

the board is pivoted at f and a steel spring s holds the board in a horizontal position the diver weighs 640N and stands still with gravity directly above a point 1.8M from F as shown calculate the moment of the weight of the diver

Answer 1

the board is pivoted at f and a steel spring s holds the board in a horizontal position the diver weighs 640N and stands still with gravity directly above a point 1.8M from F as shown calculate the moment of the weight of the diver

**Solution:**

Moment of the weight of the diver is defined as the product of the lever-arm distance d and weight force:

$$M = F \cdot d = 640N \cdot 1.8m = 1152N \cdot m$$

**Answer:** moment of the weight of the diver is $M = 1152N \cdot m$
