- 4. The minimum and maximum velocities of a moon rotating around Uranus are = v - V, and v, = v+v,. Find the eccentricity in terms of v and v,. min maxA square plate (4 m on each side) is fixed from a pivot point and can rotate around this point. The point is located on the top right corner of the square. Each of the three forces applied (one on the top, 3 N, one on the left side, 1 N, and one on the bottom, 5 N) are applied perpendicular to their respective side. Find the total torque applied by the given forces and state which direction the plate will rotate.Let us say that we have a ladder with its own length (L) and its own mass (m) this ladder just so happens to make a (θ) degree angle with a wall. The center of mass of this ladder is 1/3 of the way up from the bottom (it gets narrower towards the top). A person of mass M then decides to climb the ladder until he comes to the halfway point. Wall has no friction but the ground has on the ladder.. a) Draw this situation and label forces so you may set up the statics equations. b) Find the force on the ladder due to the ground (both x and y components) and the force on the ladder due to the wall.
