Two equal-magnitude forces are applied to a door at the doorknob. The first force is applied perpendicular to the door, and the second force is applied at 30° to the plane of the door. Which force exerts the greater torque about the door hinge? Both forces exert zero torque. the second force (applied at an angle) the first force (applied perpendicular to the door) Both forces exert equal the same non-zero torque.

A torque RF is applied on a door by pushing with a perpendicular force F at a distance R from the hinge (axis of rotation), which of the following will increase the magnitude of the torque? Mark all that apply. a. Move force F closer to the axis of rotation. b. Move force F farther from the axis of rotation. c. Apply force F parallel to the moment arm. d. Apply force F at an angle of 30 to the...

When you push a door closer to the hinges, why does it open more slowly? because you are closer to the center Now choose from one of the following options Why? a) It opens slowly, because the lever arm is shorter so the torque is large b) It opens slowly because the lever am is longer so the torque is large. c It opens slowly, because the lever asi is shorter so the torque is less. Comes from 9.2 The...

Exploration 2.2 For this Exploration, find a door at home. First apply a force perpendicular to a line through the pivot point (the door hinge) and the point of application. In other words, apply a force perpendicular to the door. Depending on the mass of the door, the force applied may not need to be very large. Just make sure you use the same force for all portions of this exercise. Then apply the force at an angle. Is the...

Imagine making a heavy door swing open by giving it a brief hard push. First, you push at its center, "push I " in the diagram Then you push near the edge, "push 2." Both pushes are equally hard akd last the same time. Which push is more effective at making the door swing open? Why? Again, lets compare the effectiveness of two pushes. This time, both pushes are applied to the same spot on the door. But...
