Question 1 3 out of 3 points What are the necessary conditions for objects in translational and rotational equilibrium? τ is torque on the object(s), F is the force on the object(s), v is the translational velocity of the object(s), and ω is the angular velocity of the object(s). Answer Selected Answers: Σ F = 0 Σ τ = 0 Question 2 3 out of 3 points If I have a bar of length 2d that is supported on a peg at a distance d from the end of the bar and I place a force of F in the downward direction at a point d/2 from the right end. What is the force (direction
