1. A uniform horizontal bar of length L = 2.0 m and weight 144 N is pinned to a vertical wall and supported by a thin wire that makes an angle of 0 = 150 with the horizontal. A mass M, with a weight of 302 N, can be moved anywhere along the bar. The wire can withstand a maximum tension of 573 N. What is the maximum possible distance from the wall at which mass M can be placed...

Rope Support In the figure, a uniform plank of length L - 6 m and weight W, 400 N is supported in a horizontal position by a support on the left end and a vertical rope on the right end. A box with a weight 1 30 N is placed on the plank at a distance x = 2.4 m from the left end of the plank. The tension in the rope is T and the support exerts a force...

4. Two vertical ropes support a 20.0 ft long bar. Each rope is inset 5.00 ft from the ends of the bar. The bar is uniform and weighs 50.0 lb. A weight of unknown size hangs from the left end of the bar, and a 100 lb weight hangs from the right end of the bar. If the tension in the left-side rope is 80.0 lb, find both the weight of the left-side hanging weight and the tension in the...

A crane is made from a uniform rigid boom of length L = 30m and weight w = 400N. The boom is sup- ported by a frictionless hinge at its lower end. Its upper end is attached to a support cable which is fas- tened behind the boom at the same horizontal level as the hinge. Adjusting the length of the support / cable adjusts the angle of the boom. In a particu- 7/TTI IN lar application, the crane is...

A uniform bar of length 3.2m and mass 4.4kg is attached to a
wall through a hinge mechanism which allows it to rotate freely.
The other end of the bar is supported by a rope of length 5.7m
which is also connected to the wall as shown above. What force in N
does the wall exert horizontally on the bar through the hinge?
(Consider a force to the right positive and a force to the left
negative.) see image below....

One end of a uniform rod of weight w = 72.5 N and length L = 2.80 m is supported by a cable at an angle of theta = 33.5 degree above the rod. The other end rests on a small frictionless support and presses into a wall as shown in the figure. Determine the magnitude n of the vertical normal force exerted by the support on the rod and find the magnitude f of the tension in the cable....

A uniform horizontal beam of length 8 m and weight 200 N is attached to a wall by a pin connection that allows the beam to rotate. Its far end is supported by a cable that makes an angle of 53degree with the horizontal. If a cable is strong enough to withstand T= 1200 N how heavy person can walk to the end of the beam? When that person was at the 0.75 distance from the wall, find: a. the...

In the figure, a uniform beam of weight 550 N and length 2.3 m is suspended horizontally. On the left it is hinged to a wall; on the right it is supported by a cable bolted to the wall at distance D above the beam. The least tension that will snap the cable is 1100 N What value of D corresponds to that tension? Number Units im The number of significant digits is set to 2, the tolerance is +/-1%
