SSM Figure 5-66a shows a mobile hanging from a ceiling; it consists of two metal pieces (m1 = 3.5 kg and m2 = 4.5 kg) that are strung together by cords of negligible mass. What is the tension in (a) the bottom cord and (b) the top cord? Figure 5-66b shows a mobile consisting of three metal pieces. Two of the masses are m3 = 4.8 kg and m5 = 5.5 kg. The tension in the top cord is 199 N. What is the tension in (c) the lowest cord and (d) the middle cord?

- A climbing anchor consists of two strands of nylon webbing clipped to bolts in the rock. The webbing is clipped into the rope at the other end, with the webbing making angles of 22° and 35° with the vertical. What is the tension in each of the webbing strands if the combined mass of the rope and climber is 85 kg?arrow_forwarda mobile hanging from a ceiling; it consists of two metal pieces (m1 3.5 kg and m2 4.5 kg) that are strung together by cords of negligible mass.What is the tension in (a) the bottom cord and (b) the top cord? a mobile consisting of three metal pieces.Two of the masses are m3 4.8 kg and m5 5.5 kg.The tension in the top cord is 199 N.What is the tension in (c) the lowest cord and (d) the middle cord?arrow_forwardA wracking ball is suspended below two cables each at an angle with the horizontal.

- A wedge with mass M rests on a frictionless m horizontal tabletop. A block with mass m is placed on the wedge and a horizontal F force F is applied to the wedge. There M is no friction between the block and the wedge. For a = "/7, what must the magnitude of F be if the block is to remain at a constant height above the tabletop? (g is the magnitude of the gravitational acceleration. Take m = 1 kg, M = 5 kg and g = 10 m/s².) %3D (a) 29 N (b) 35 N (c) 44 N (d) 60 N (e) 104 Narrow_forwardA picture frame hung against a wall is suspended by two wires attached to its upper corners. If the two wires make the same angle with the vertical, what must this angle be if the tension in each wire is equal to 0.75 of the weight of the frame? (Ignore any friction between the wall and the picture frame.)arrow_forwardThe figure shows a section of a cable-car system. The maximum permissible mass of each car with occupants is 2200 kg. The cars, riding on a support cable, are pulled by a second cable attached to the support tower on each car. Assume that the cables are taut and inclined at angle 0 = 39°. What is the difference in tension between adjacent sections of pull cable if the cars are at the maximum permissible mass and are being accelerated up the incline at 0.85 m/s²?

- A large wrecking ball of mass m is resting against a wall. It hangs from the end of a cable that is attached at its upper end to a crane that is just touching the wall. The cable makes an angle of θ with the wall. Ignoring friction between the ball and the wall, find the tension in the cable.arrow_forwardThe figure shows a container of mass m₁ = 1.7 kg connected to a block of mass m₂ by a cord looped around a frictionless pulley. The cord and pulley have negligible mass. When the container is released from rest, it accelerates at 1.0 m/s² across the horizontal frictionless surface. What are (a) the tension in the cord and (b) mass m₂?

- A car of mass m₁ 1000 kg is connected to a trailer of mass m2 = 400 kg by a taut inextensible cable. The car's engine provides a constant forward driving force Fx = 7000 N, which causes the car-plus-trailer to accelerate forwards along the horizontal x-axis. The tension of the cable produces a force on the trailer and also a force on the car. You may assume that the magnitude of the two forces is the same. You may also ignore friction. What is the tension in the cable joining the car to the trailer? Give your answer by entering a number, correct to an appropriate number of significant figures, in the empty box below.arrow_forwardA block having a weight of G is placed on the rough surface of the triangular prism ABC.

A person is pushing on the back of the sledge with a force of 80 newtons, parallel to and up the slope. One end of a rope is attached to the front of the sledge. This rope is held taut by a child. The rope makes an angle of 20◦ with the upward slope. The child is pulling the rope with a force of 25 newtons and the sledge is on the point of slipping up the slope. Take the unit vector i to be in the direction up the slope and the unit vector j to be in the direction perpendicular to the slope and upwards. Express the forces in component form, in terms of unknown magnitudes where appropriate. Hence find the coefficient of static friction between the sledge and the snow, to two significant figures.arrow_forward
