Final answer:
Verifying torque on a bolt involves applying the correct level of force at the appropriate distance from the bolt to achieve the required level of torque, as per the formula for torque in physics.
Step-by-step explanation:
Verifying the torque of a canister tie down bolt to ensure it has at least 60 foot pounds of torque and that the washer is properly seated is a practical application of physics. Considering a similar scenario, if a mechanic needs to tighten cylinder head bolts to a torque of 62.0 N.m, they can use the formula τ = r * F * sin(θ), where τ is torque, r is the length of the wrench, F is the force applied, and θ (theta) is the angle between the force vector and the lever arm, which in this case is 90 degrees, making the sin(θ) equal to 1.
For example, if a mechanic uses a wrench of length 0.20 m (20 cm), they would need to exert a perpendicular force calculated as F = τ / r = 62.0 N.m / 0.20 m, which results in a force of 310 N. In summary, it's critical to apply the correct force at the appropriate distance to achieve the specified torque.
