Draw the free-body diagram for the truss. A is a pin and B is a rocker. (Part A)

Draw the vectors starting at the black dots. The location and orientation of the vectors will be graded. The length of the vectors will not be graded.

Part B

Draw the free-body diagram for the beam. A is a pin.

Draw the vectors starting at the black dots. The location and orientation of the vectors will be graded. The length of the vectors will not be graded.

Part C

Draw the free-body diagram for the man and load. The man stands on a smooth floor. Neglect his weight and friction force between the floor and the man.

Draw the vectors starting at the black dots. The location and orientation of the vectors will be graded. The length of the vectors will not be graded.

Part D

Draw the free-body diagram for the beam. B is a roller.

Draw the vectors starting at the black dots. The location and orientation of the vectors will be graded. The length of the vectors will not be graded. Double-click on the black dot to indicate the direction of the moment. To change the direction click on the dot one more time.
