Challenge Problems
Push your limits with advanced challenges
A beam is supported at its center with two weights of 150 N and 200 N placed at different distances from the pivot. Calculate whether the beam is in rotational equilibrium.
💡 Hint: Use the distance each weight is from the pivot to calculate their respective torques.
Design a basic structure (like a table) ensuring both translational and rotational equilibrium under a specific load. Explain the forces acting on it.
💡 Hint: Consider how the design's geometry can affect stability.
