An oil pipeline is supported at 6-ft intervals by vertical hangers attached to the cable shown. Due to the combined weight of the pipe and its contents the tension in each hanger is 400 lb. Knowing that, do 10 ft determine (a) the maximum tension in the cable, (b) the distance de dsdcdp -5 @ 6 ft = 30 ft Adidation
One end of a cord is fixed and a small 0.550-kg object is attached to the other end, where it swings in a section of a vertical circle of radius 1.00 m, as shown in the figure below. When θ = 30.0°, the speed of the object is 6.50 m/s. One end of a cord is fixed and a small 0.550-kg object is attached to the other end, where it swings in a section of a vertical circle of radius...
1. A solid uniform 45-kg ball of radius 16.0 cm is supported against a vertical, frictionless wall with a string of length 30.0 cm as shown below. (10 pts) a) Find the tension in the string. b) Find the force the wall exerts on the ball. K30,0 cm
The 2-kg pendulum bob moves in the vertical plane with a velocity of 10 m/s when 30°. Determine the initial tension in the cord and also at the instant the bob reaches u 0 - 60°. Neglect the size of the bob. (Use principle of work and energy to calculate vg-60 2 m
One post of a volleyball net is shown solidly supported in the ground. There are two Fi forces exerted horizontally in the yz plane, one at B and one at C, due to the tension in the volleyball net. There are two strings attached at B and to the ground with a force of F2 in them. Calculate: F1 2 ft 4 Fi 5 ft F2 E(3, 7, 0)ft COLLAPSE IMAGES F1-44 lb F2 = 120 lb
1. (8 points) A 190-k column load is to be supported on a 10-ft square, 3-ft deep spread footing underlain by young, normally consolidated sandy soils. The results of a representative CPT sounding at this site are as follows: Depth (ft) 21.0-40.0 0.0-6.0 6.0-10.0 10.0-18.0 18.0-21.0 e (kg/em2 The groundwater table is at a depth of 12 ft; the unit weight of the soil is 124 Ib/t above the groundwater table and 130 lb/ft below. Using Schmertmann's method (not the...
7. AS kg ball is initially at rest on a horizontal frictionless surface as shown to the right. A hard plastic cube of mass 0.5 kg slides across the surface at a speed of 26 ms and strikes the ball The figure below shows a graph of the force exerted on the ball by the cube as a function of time. Oslo Force (x10'N) 10 2.0 10.0 4.0 6.0 8.0 Time (x10's) A) Determine the total impulse given to the...
due in 30 min 8. (10 points) Picture taken from problem 19-21. The spool has a weight of 30 lb and a radius of gyration ko=0.45 ft. A cord is wrapped around the spool's inner hub and the end of the chord is subjected to a horizontal force P = 5 lb. Assume the spool rolls and slips. The coefficient of friction between the spool and the ground is uk = 0.1. Determine the spool's angular velocity in 4 s...
