The slabhas length L = 38.7 m, thickness T = 6.61 m, andwidth W = 13.7 m, and 1.0 cm³ of it has a mass of 3.2%3D%3Dg. The coefficient of static friction between slab andbedrock is 0.356. (a) Calculate the component of thegravitational force on the slab parallel to thebedrock surface. (b) Calculate the magnitude of thestatic frictional force on the slab. By comparing (a)and (b), you can see that the slab is in danger ofsliding. This is prevented only by chance protrusionsof bedrock. (c) To stabilize the slab, bolts are to bedriven perpendicular to the bedrock surface (twobolts are shown). If each bolt has a cross-sectionalarea of 7.44 cm2 and will snap under a shearingstress of 3.14 x 108 N/m2, what is the minimumnumber of bolts needed? Assume that the bolts donot affect the normal force.II
