... rotation to once per 28.0 h by exerting an opposing force at and parallel to the equator. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.00×107 N (a little greater than a Saturn V rocket’s thrust). How long must Zorch push with this force to accomplish his ...

... And the force exerted by the wall on the beam, R. (The wall is pushing the beam up and out.) Think about this as an application of Newton’s Third Law. R must be acting in that way to counteract the Tension in the cable. (a) Let us first sum the torques. The pivot point is the end of beam where it me ...

... Solution The pivot point is at the hinges of the door, opposite to where you were pushing the door. The force you used was 50N, at a distance 1.0m from the pivot point. You hit the door perpendicular to its plane, so the angle between the door and the direction of force was 90 degrees. Since = r x ...
