A person is pushing on a uniform block of wood as shown in the figure and parameter table. The block of wood has mass 140 kg and a coefficient of static friction of Hs, w = 0.3. Assume the person only exerts a horizonatal force on the block of wood, and their shoes have a coefficient of static friction Hs,p = 0.4. What is the minimum mass the person needs to be able to move the block? Also, what is the maximum value of 4a, w that the wood could have and still slide instead of tip if pushed at the same location?

You pick up a boiled egg using kitchen tongs as shown. The egg is 60 g and it hasa static friction coefficient of 1.4 with the tongs. Determine the minimum magnitude of force Fyou need to apply so the egg does not fall. Assume you won’t break/crack the egg.
In the figure, a rectangular slab of slate rests on a bedrock surface inclined at angle 0 = 25.8°. The slab has length L = 33.9 m, thickness T = 8.91 m, and width W = 11.9 m, and 1.0 cm³ of it has a mass of 3.2 g. The coefficient of static friction between slab and bedrock is 0.371. (a) Calculate the component of the gravitational force on the slab parallel to the bedrock surface. (b) Calculate the magnitude of the static frictional force on the slab. By comparing (a) and (b), you can see that the slab is in danger of sliding. This is prevented only by chance protrusions of bedrock. (c) To stabilize the slab, bolts are to be driven perpendicular to the bedrock surface (two bolts are shown). If each bolt has a cross-sectional area of 7.96 cm² and will snap under a shearing stress of 3.68 × 108 N/m², what is the minimum number of bolts needed? Assume that the bolts do not affect the normal force. (a) Number (b) Number (c) Number Units Units Units
