Determine the magnitude and direction of the couple shown.
Three parallel forces act on the rim of the tube. If it is required that the resultant force FR of the system have a line of action that coincides with the central z axis, determine the magnitude of FC and its location 
on the rim. What is the magnitude of the resultant force FR?
= 56.3°, R = 861 lb = 54.0°, R = 1000 lb = 36.0°, R = 1000 lb = 36.9°, R = 861 lb
A force of 50 N is applied to the handle of the door as shown. Determine the projection of the moment of this force about the hinged axis z. Neglect the size of the doorknob. Suggestion: Use a scaler analysis.
The wind has blown sand over a platform such that the intensity of load can be approximated by the function 
. Simplify this distributed loading to a single concentrated force and specify the magnitude and location of the force measured from A.
The pole supports a 22-lb traffic light. Using Cartesian vectors, determine the moment of the weight of the traffic light about the base of the pole at A.
