Question

Find the net torque . The answer is 4Fd . I need the proper explanation. Plz answer fast...​

Answer 1

Answer:

The formula for determining torque, τ is τ = r × F, where r is the lever arm and F is the force. Remember, r, τ, and F are all vector quantities, thus the operation is not scalar multiplication, but a vector cross product

Answer 2

Answer:

Find the net torque on the wheel in the figure below about the axle through O perpendicular to the page, taking a = 8.00 cm and b = 20.0 cm. The total torque on an object is the sum of the individual torques. Remember that d is the perpendicular distance from the rotation axis to the line of action of the force , called the moment arm or lever arm of . We have the following. This represents a torque vector that points into the plane of the page, and results in a turning by the force.
