- MY NOTES ASK YOU Consider the figure below. (Let w, = 130 N and w, = 55.0 N.) W, W2 (a) What is the minimum force of friction required to hold the system of the figure above in equilibrium? (b) What coefficient of static friction between the 130-N block and the table ensures equilibrium? (Enter the minimum acceptable coefficient of friction.) (c) If the coefficient of kinetic friction between the 130-N block and the table is 0.212, what hanging weight should replace the 55.0-N weight to allow the system to mc constant speed once it is set in motion?Determine whether the 15-kg block shown is in static equilibrium under the loadings shown, and report the magnitude of the friction force (in Newton) when P = 730 N and 0 = 46 degrees at the state of static equilibrium. The coefficients of static and kinetic friction between the block and the rough inclined surface are shown in the picture. Report the friction force as positive when it is directed downward, and negative when it is directed upwards. 500 N Ms = 0.35 Mk = 0.25 35° ᎾSolve the following problem (NOTE: Use any reasonable DATA not given in the problem.)
- Consider the figure above, where a rigid beam of negligible mass and 10 m long is supported by a cable attached to a spring. When NO block is hung from the beam, the length L (cable-spring) is equal to 5 m. Assume that immediately after block (weight of 260 N) is hung at the end of the beam the spring does not stretch, calculate the tension under this assumption. Using this tension find how much the spring stretches. Express the amount the spring is stretched in cm. k =8275 N/m.Two boxes are stacked as shown in the diagram below. The bottom box has a mass of 3.5 kg and the top box has amass of 1.5 kg. They are pushed up a ramp inclined at 15° by an applied force of 25 N, applied to the lower boxand directed parallel to the ramp. The coefficient of kinetic friction between the ramp and the bottom box is 0.12.Determine the minimum coefficient of static friction required to keep the top box in place on the bottom box.Consider the figure below. (a) Find the tension in each cable supporting the 640-N cat burglar. (Assume the angle 0 of the inclined cable is 31.0°.) inclined cable horizontal cable N vertical cable (b) Suppose the horizontal cable were reattached higher up on the wall. Would the tension in the inclined cable increase, decrease, or stay the same? O increase decrease O stay the same

An additional (blue rope) also connec ts the strut to the wall attached at an angle 01. A load of weight W is hanging from the strut; the load makes an angle 02 with the strut as shown in the diagram. In order to stabilize the system, and additional force needs to be applied. That force, which is labeled C in the diagram, makes an angle p with respect to the strut as shown. What is o?
