A worker stands a distance d = 0.325 m from the left end of a plank as shown in the figure. The plank is supported by three cords. Find the tension in each cord (in N). Assume the plank is uniform, with length L = 2.00 m and mass 29.5 kg, and the weight of the worker is 720 N. (Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.)...
(a) A worker stands a distance d = 0.425 m from the left end of a plank as shown in the figure. The plank is supported by three cords. Find the tension in each cord in N). Assume the plank is uniform, with length L = 2.00 m and mass 30.5 kg, and the weight of the worker is 685 N. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in...
A 69 kg construction worker is standing on an 18.0 kg plank. The plank is 4.5 m long and it is suspended by vertical cables at each end. If the worker stands 2.80 from the right end of the plank, what is the tension in right cable? Give your answer in newtons (N) and with 3 significant figures. Please Show Work :)
A uniform plank that is 4.00 m long has a mass of 7.00 kg. The plank is supported by two sawhorses, one 3.56 m from the right end of the plank and the other 1.50 m from the right end of the plank. A cat of mass 2.63 kg is sitting on the plank at a distance of 1.75 m from the right end of the plank. (a) Draw a free body diagram showing the four forces acting ON the...
(a) A person stands a distance d 0.425 m from the left end of a plank as shown in the figure. The plank is supported by three cords. Find the tension in each cord (in N). Assume the plank is uniform, with length L 2.00 m and mass 31.5 kg, and the weight of the person is 690 N. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) 40.0...
A gymnast with mass m-41 kg is on a balance beam that sits on (but is not attached to) two supports. The beam has a mass m - 107 kg and length L 5 m. Each support is 1/3 of the way from each end. Initially the gymnast stands at the left end of the beam. 1j What is the force the left support exerts on the beam? 2) What is the force the right support exerts on the t...
A 100 kg construction worker sits down at the end of 4.0 m long, 1000 kg steel beam which is supported by a wall and a cable attached at 1m and 45° to the wall, as shown below. What is the minimum strength in Newtons) that the cable must be rated at to support the load? 45° 1 m 3 m
An 73.9 kg construction worker sits down 2.16 m from the end of a 1415.9 kg steel beam to eat his lunch. The cable supporting the beam is rated at 16576 N. Should the worker be worried? (To answer that question calculate the tension in the cable. Use θ=32°, L=6.8 m.)
dont know what im doing wrong Suppose a 28.4-kg child sits 0.67 m to the left of center on the same seesaw as the problem you just solved in the PRACTICE IT section. A second child sits at the end on the opposite side, and the system is balanced. (a) Find the mass of the second child. 8.55 kg (b) Find the normal force acting at the pivot point. 362 Your answers to part (a) and (b) are not consistent....
A person carries a plank of wood 2.00 m long with one hand pushing down on it at one end with a force F, and the other hand holding it up at .500 m from the other end of the plank with force F2 . If the plank has a mass of 20.0 kg and its center of gravity is at the middle of the plank, what are the magnitudes of the forces F, and F? F1 = 196 N;...
