Problem 2.17 Figure 2.28 shows a simple experimental method to determine the coefficient of static friction between surfaces in contact. This method is applied by placing a block on a horizon- tal plate, tilting the plate slowly until the block starts sliding over the plate, and recording the angle that the plate makes with the horizontal at the instant when the sliding occurs. This critical angle () is called the angle of repose. At the instant just before the sliding occurs, the block is in static equilibrium. Fig. 2.28 Problem 2.17 Through force equilibrium, show that the coefficient of static friction just before motion starts is u = tan 0c.

A crate, in the form of a cube with edge lengths of 1.2 m, contains a piece of machinery; the center of mass of the crate and its contents is located 0.123 m above the crate's geometrical center. The crate rests on a ramp that makes an angle 0 with the horizontal. As 0 is increased from zero, an angle will be reached at which the crate will either tip over or start to slide down the ramp. If the coefficient of static friction Hs between ramp and crate is .55, (a) does the crate tip or slide? (b) At what angle 0 does this occur? If us = 0.94, (c) does the crate tip or slide? (d) At what angle 0 does this occur? (Hint: At the onset of tipping, where is the normal force located?)
Example 1 Suppose a block with a mass of 2.50 kg is resting on a ramp. If the coefficient of static friction between block and ramp is 0.350, what maximum angle can the ramp make with the ng sin 8 mg cos 8e the horizontal before the mg block starts to slip down?

Can someone please help me to solve the following question showing all needed work and formulas along with needed diagrams. Please and thank you!
In a factory, a 500 kg pallet load of bricks is routinely moved along a smooth concrete surface by a vehicle and arope. The rope makes an angle of 20° relative to the surface. The coefficient of static friction between the pallet andthe surface is µs = 0.18. As the engineer on duty, you need to advise the factory how strong the rope needs to be.The rope manufacturer can tell you what tensile strength each rope has in units of Newtons. What rope do youchose? If you can could you possibly draw a diagram with it? Because I'm confused with how they've described the rope and its angle to the surface.
Please answer within 10 minutes, thank you!
A 68 kg credenza is being pushed to move it. Due to use of sliders on the right side "feet," the coefficient of static friction at those feet, labeled B, is .2 while the coefficient of static friction at the feet labeled A is .4. Assuming impending motion, find the minimum force needed to move the credenza. Draw a clear and complete FBD before setting up your equations. Make sure your equations are clear before solving them! 0.8 m 0.7 m 0.6 m 0.6 m
A heavy cask (full of wine!) sits on an inclined plane. It is held in place by a rope that is attached to the cask and to a hook further up the inclined plane (at A). The rope comes off of the cask tangent to the cask. The mass of the cask is 40 kg, and the coefficient of static friction between the inclined plane and the cask is 0.25. What is the maximum value of 0 just before the cask begins to slip? Also, what is the tension in the rope when slipping is impending? Finally, if the inclined plane became icy, and the rope didn't break as the cask slipped, what would be remarkable about the lines of action of the W, N and T force vectors once equilibrium was re-established? 0.70 m 40
