Uniform Door Torque
A 20.0-kg uniform door has a width of 1.20 m and a height of 2.50 m. The door is mounted on a post by a pair of hinges, marked 1 and 2 in the figure, at the topand bottom of the door. An external force of 60.0 N, at an angle of 30.0° above the horizontal, is applied to the small doorknob, as shown in the figure. Thedoorknob is 1.00 m above the bottom of the door.
(b) Find the SUM of the 
components ofthe forces that hinges 1 and 2 together exert on the door.
I already found the x component of the top hinge to be -53.4N if that helps any.

A uniform 24 kg door that is 2.5 m high by 0.80 m wide is hung from two hinges that are 20 cm from the top and 20 cm from the bottom. If each hinge supports half the weight of the door, find the magnitude and direction of the horizontal components of the forces exerted by the two hinges on the door. (Take the direction of forcing the door away from the hinges to be positive and the direction of...

#4 please
A uniform sheet of metal in the shape of a hemisphere of radius 1 m is used as a sign. The hemisphere has a mass of 200 kg and is suspended by two vertical wires attached to points along its horizontal diameter. One wire is attached to the left end of the diameter and the other is attached to a point three-quarters of the way to the other end. What is the tension in each wire? A ladder...

Surface Tension and Bubbles Surface tension is a force caused by the attraction of liquid molecules on a boundary surface for each other. It acts tangential to the surface and is modeled as a single number, the surface tension Consider a square film on a wire frame. The bottom edge is movable and, when the frame is vertical, as shown, the surface tension of the film pulls...
