the vertical post is secured by three cables. the cables are pre-tensioned so that the resultant of the cable forces f, q, and p is directed along the z-axis. if f = 120 lb, find p and q. ans. p = 74.3lb, q = 69.9l

The h110 ft tall communication tower is supported by three cables at A and a ball-and-socket support at O. Cable AB is pre-tensioned with a magnitude TAB = 4 kips. The coordinates of points B, C, and D in the ground (z,y) plane are: B = (25,45) ft C = (-15,20) ft D = (-5, -15) ft Determine the magnitude of the tension in cables AC and AD and the normal force in tower AO.

Determine the resultant of the forces acting on the dam as shown.

A transmission tower is held by three guy wires attached to a pin at A and anchored by bolts at B, C, and D. If the tower produces and upward force from O to A of 6000 lb, then calculate the magnitude of the tensions in cables AB, AC, and AD.

240 lb B 2. Find the horizontal and vertical forces at Point C as it acts on Member BD. D 45° 450 E -8'-

The combined action of the three forces on the base at O may be obtained by establishing their resultant through O. Determine the magnitudes of R and the accompanying couple M. Assume F₁ = 350 lb, F₂= 620 lb, F₂ = 520 lb, a = 5.4ft, b = 2.9 ft. c = 4.0 ft, and 0 = 50° Answers: R= i 1091.134 lb M= i 9719.344 lb-ft

find the sum of the moments of the Forces in kN.m about Point O, (positive in the counter- clockwise direction). F1 = 60 kN and F2 = 22 kN. 15 m 9 m F1 kN F2 KN

If the resultant of the forces shown passes through point A, determine the magnitude of the unknown pulley tension T2. The pulley is welded to the frame and is therefore not free to rotate. 1.3 m 260 N Answer: T₂ = i 0.4 m A T₂ 827.32 1.7 m 59° 1440 N B 0.70 m 1.40 m 660 N 240 N N
