Challenge Problems
Push your limits with challenges.
Question 1
Consider a cuboidal object where traction forces act on all faces. If the traction on the front face is known, describe how you would find the resultant torque on the object.
💡 Hint: Think about how the distance of the applied force influences torque.
Question 2
A beam supports a load from two different points. Describe how you would calculate the effect of each point on the overall angular momentum of the system.
💡 Hint: Be sure to consider how various distances from the pivot influence the overall rotational effect.
