- Fy m +x P On the left a mass, 17.9 kg, is at rest. Force Pis acting on the mass in the (Fx) direction as shown. The coefficient of static friction between the mass and the surface is μ = 0.855. The coefficient of kinetic friction between the mass and the surface is µ = 0.565. What is the greatest force P that can be applied and the mass will remain at rest?What is T?answer c please
- A painter stands on a scaffold hung by its ends from two vertical ropes A and P, 6 m apart. The scaffold weighs 200 N. The tension in A is 750 N and that in Pis 200 N. a) What is the weight of the painter? b) How far from A is he standing?The crate A weighs 780 lb. Between all contacting surfaces, μs = 0.34 and μk = 0.29. Neglect the weights of the wedges. What force F is required to move A to the right at a constant rate? Wedge angle is 6 degrees.A 853 N magician (note: this is weight, not mass) is freeing himself from some shackles while suspended above a swimming pool filled with alligators. Two ropes are suspending the magician. The left rope makes an angle of 42 above the horizontal and points up and to the left. The right rope makes an angle of 78 above the horizontal and points up and to the right. Calculate the tension in the left rope, in N. (Please answer to the fourth decimal place - i.e 10.5432)
- In the figure, block M2 is sitting on a table and is connected by mass-less chords to block M1 and to a vertical wall. The coefficient of static friction between M2 and the table is Us=0.60. Block M1 has a mass of 8 kg. The angle made by the chord and the wall is 55 degrees. What minimum mass must block M2 have in order to remain stationary and not slide?A mountain climber, in the process of crossing between two cliffs by the rope, pauses to rest. She weight 535 N. She is closer to the left cliff than to the right cliff. The left rope makes 600 and the right rope makes 800 with the vertical. Find the tensions in the rope to the left and to the right of the mountain climber.A horizontal force F pushes against a block of mass m. The mass m in turn pushes against a bigger block of mass M. There isn't friction any between the larger block and the table, but there is friction in between the blocks (coef. of static friction is μs). What's the smallest force F that will hold the smaller mass m m against the larger mass M without letting the smaller mass m fall down?
