A 3.00--long, 200-, uniform rod at the zoo is held in a horizontal position by two ropes at its ends (the figure ). The left rope makes an angle of 150 with the rodand the right rope makes an angle with the horizontal. A 91- howler monkey (Alouatta seniculus) hangs motionless 0.50 from the right end of the rod as he carefullystudies you.

Answer #1

Σ S =0

Tl sin150 * 3m = 180 N * 1.5 +91 *0.5

Tl = 210.33 N

1) vertial , Σ Fv = 0

(180 + 91 ) - 210.33*sin150 = 165.835

2) horizontal

210.33*cos150 = −182.1511

θ = arctan(165.835/182.1511) = 42.31 degree

    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...

    One end of a uniform 4.40-m-long rod of weight Fg is supported by a cable at an angle of θ = 37° with the rod. The other end rests against the wall, where it is held by friction as shown in the figure below. The coefficient of static friction between the wall and the rod is μs = 0.580. Determine the minimum distance x from point A at which an additional object, also with the same weight Fg, can be...
