The Attempt at a Solution
I'm confused to whether or not there is ever any cases in which cos is substituted for sin?
Torque is a measure of the twisting or rotating force on an object. It is important in physics because it helps us understand how forces act on objects to cause rotational motion.
The torque equation is T = r x F x sinθ, where T is torque, r is the distance from the pivot point to the point where the force is applied, F is the applied force, and θ is the angle between the force and the lever arm. To calculate torque, simply plug in the values for these variables and solve for T.
Torque is typically measured in newton-meters (Nm) or foot-pounds (ft-lb), depending on the system of units being used.
The direction of the force affects the torque through the angle θ in the torque equation. The sine function in the equation accounts for the direction of the force relative to the lever arm. A force applied perpendicular to the lever arm will have the greatest torque, while a force applied parallel to the lever arm will have no torque.
Yes, the torque equation can be rearranged to solve for any of the variables. For example, if you know the values for torque, distance, and angle, you can solve for the force by rearranging the equation to F = T / (r x sinθ).
