Questions & Step-by-Step Solutions
A torque of 40 Nm is required to rotate a wheel. If the radius of the wheel is 0.4 m, what is the force applied tangentially?
Step 1: Understand that torque is the measure of how much a force acting on an object causes that object to rotate.
Step 2: Identify the formula for torque, which is Torque = Force x Radius.
Step 3: Rearrange the formula to find Force: Force = Torque / Radius.
Step 4: Plug in the values: Torque = 40 Nm and Radius = 0.4 m.
Step 5: Calculate the Force: Force = 40 Nm / 0.4 m.
Step 6: Perform the division: 40 divided by 0.4 equals 100.
Step 7: Conclude that the force applied tangentially is 100 N.
Torque and Force Relationship – This concept involves understanding the relationship between torque, force, and radius, where torque is the product of force and the radius at which the force is applied.
