The rectangular plate is supported by
the brackets at A and B and by a wire
CD. Knowing that the tension in the
wire is 200 N, determine the moment
about A of the force exerted by the
wire at C.
The L-shaped frame ACD is supported by joints at A and D and is supported by a single cable GBH that passes through a ring at B and attached to hooks at G and
H. Knowing that the tension in the cable is T-550 N, determine the moment about the diagonal AD of the force exerted on the frame by portion BG of the cable
following the Parts (A) - (G) below. The length variables are a 0.5 m,b=2 m, c = 0.75 m, d = 1 m, e = 1 m, respectively.
NOTE 1: Pay extra attention to the arrangement of the x, y and z-axes: y-axis vertical, z-axis horizontal from right to left, and x-axis horizontal from the left to right. This is
a legitimate right-handed system, displayed differently from the view used in our textbook.
NOTE 2: Give the answer up to THREE significant digits. For example:
0, 0.0, 0.00 (any will do) for ZERO
12300 (round down) for 12335
12400 (round up) for 12378
NOTE 3: Although the intermediate answers shoud be provided up to 3 significant digits, do not use this answer to calculate the…
