Q1: The 100 tb force of Figure below is the resultant of the couple and four forces, three of which are shown in the diagram. Determine the fourth force and locate it with respect to point A. 100b 50b 4 120n -ib 20b 4" 40b

Add the following forces to find the resultant force. V1 = 150 g @ 470 V2 = 550 @ 324° V3 = 350 g @ 215° V4 = 250 @ 172° V5 = 450 g @ 285°

The pipe assembly is subjected to the action of a wrench at B and a couple at A. (Figure 1) Simplify this system to a resultant wrench. Set F = 40 N.  a) Determine the components of the resultant force of the wrench. Enter the x, y, and z components of the force separated by commas. Express your answers in newtons to three significant figures.  b) Determine the components of the resultant moment of the wrench. Enter the x, y, and z components of the moment separated by commas. Express your answer in newton-meters to three significant figures.  c) Specify the location of the wrench along the axis of pipe CD��, measured from point C�. Express your answer to three significant figures and include the appropriate units.
