Questions & Step-by-Step Solutions
A torque of 5 Nm is applied to a wheel. If the radius of the wheel is 0.25 m, what is the force applied tangentially?
Step 1: Understand the formula for torque, which is τ = F × r, where τ is torque, F is force, and r is the radius.
Step 2: Identify the values given in the question: Torque (τ) = 5 Nm and Radius (r) = 0.25 m.
Step 3: Rearrange the formula to solve for force (F): F = τ / r.
Step 4: Substitute the values into the formula: F = 5 Nm / 0.25 m.
Step 5: Calculate the force: F = 20 N.
Torque – Torque is the rotational equivalent of linear force, calculated as the product of force and the radius at which the force is applied.
Tangential Force – Tangential force is the component of force that acts along the edge of a circular path, responsible for causing rotational motion.
Units of Measurement – Understanding the units of torque (Nm), force (N), and radius (m) is crucial for solving problems involving rotational dynamics.
