PLEASE PUT SOLUTION (WHY) // WHY THE REASON OF THAT ANSWER (?) 1. What should be done to increase the generated torque on a bar, with one end fixed to a point, without increasing the applied force? A. Make the moment arm shorter. B. Increase the weight of the moment arm. C. Move the axis of rotation closer to the point where force is applied. D. Increase the length of the moment arm. 2. How will the generated torque change if you move the axis of rotation from the middle of a bar to its left end, given that the applied force is applied at its right end? A. Torque will be doubled. B. Torque will increase 1.5 times the original. C. Torque will remain the same. D. Torque will be halved.

Please help me! A uniform beam of weight 12 N and length 10 m is mounted by a small hinge on a wall. The beam is held in a horizontal position by a vertical rope at the location as shown. (I attached a picture of the diagram) A.) What is the gravitational torque about the beam's left end, in N·m? (Pay attention to the sign.) B.) What is the torque by the tension force about the beam's left end, in N·m? (Pay attention to the sign.) C.) What is the magnitude of the tension force in the rope, in Newtons?

Answer the following concisely, in no more than three sentences. 1. A massless wire connects two masses, one of which is exactly twice the other. If theconnecting wire has length L, should a support be placed at a distance L/3 from the largermass to achieve equilibrium? The mass of the wire is assumed to be negligible. 2. Are projectiles subject to constant acceleration in two dimensions? 3. Explain in detail why a spinning ice-skater's angular speed increases when she pulls in herarms closer to her body. 4. Stand facing the edge of an open door, one foot on each side of the door. You will find thatyou are not able to stand on your toes. Why? 5. Two identical pool balls are shot directly at one another at the same speed. Describe the ball'smotions after they collide, assuming that frictional forces may be neglected and the collisionis completely elastic.
