The force of magnitude f acts along the edge of the triangular plate. determine the moment of f about point o. find the general result and then evaluate your answer if f = 260 n, b = 580 mm, and h = 370 mm. the moment is positive if counterclockwise, negative if clockwise.

The moment is 81.102 k N-m in clockwise.

Explanation:

Given that,

Force = 260 N

Side = 580 mm

Distance h = 370 mm

According to figure,

Position of each point

We need to calculate the position vector of AB

We need to calculate the unit vector along AB

We need to calculate the force acting along the edge

We need to calculate the net moment

Put the value into the formula

Put the value into the formula

Negative sign shows the moment is in clockwise.

Hence, The moment is 81.102 k N-m in clockwise.
