Final answer:
The moment of force F around point A can be determined by calculating the torque, which is the product of the lever arm and the perpendicular force.
Step-by-step explanation:
Determine the moment of force F around point A
To determine the moment of force F around point A, we need to calculate the torque. Torque can be calculated using the formula T = rF sin θ, where r is the lever arm and F is the perpendicular force. In this case, the torque is equal to the product of the lever arm (1.50 m) and the force (250 N), giving us a value of 375 N·m.
