Question

Find the magnitude of the torque about P if an F=28-lb force is applied as shown.
(ft-lb)

Answer 1

To find the magnitude of the torque about point P when a force of 28 lb is applied, use the formula T = rFsinθ, where T is the torque, r is the distance, F is the force, and θ is the angle between the force and the lever arm.

Step-by-step explanation:

To find the magnitude of the torque about point P when a force of 28 lb is applied, we need to know the distance between the point of application of the force and point P. The magnitude of the torque can be calculated using the formula T = rFsinθ, where T is the torque, r is the distance, F is the force, and θ is the angle between the force and the lever arm.

Let's say the distance r is 2 feet. Plugging in the values, we get T = 2 ft * (28 lb) * sin(θ).

Now, if you have the value of θ, you can plug it into the formula and calculate the magnitude of the torque.
