The weight W causes tension of 170 N in cable CD. If d = 2.7 m, what is the moment about the z-axis due to the force exerted by the cable CD at point C? (0,3,0) m W D (3, 0, 10) m (12, 10, 0) m

(a) Determine the magnitudes and coordinate direction angles of F3 so that the resultant force of the three forces is zero. Refer figure Ql(a) below. Q1. F, F1 = 400N 40 30 F2 = 600N Figure Q1(a) Q1 the moment(MB) of this force about point B. (b) Figure Q1 (b) shows the pipe assembly is subjected to the 100N force. Determine 400 mm 300 mm 200 mm 200 mm 250 mm 40° 30 F = 100N Figure Q1(b)

In the figure below, set up an equation related to the moment (M) about the paired force (F).

The roof is supported by the bracket at O and by two cables as shown in the Fig. below.  If the cables exert forces FAB = 100 N and FAC = 120 N on the wall hook at A as shown in Fig.;  Determine the moment about O  (the origin) of the forces exerted by the cables at B and C.

If the moment of the five forces about point (A ) is ( - 4800 ), find the amagnitude of the force ( F,). Also find the moment about point (0). 6= 200N T-750 N
