A crate, which has a weight of W, is placed on an inclination. The force P is applied to prevent the crate from sliding down the inclination. a) Determine the minimum required force P, if the coefficient of static friction is u31. b) Determine the friction force (in magnitude) acting at the bottom of the crate if the force P=P1 and the coefficient of statie friction is µs1. c) Determine the minimum required force P, if the coefficient of static friction is u32. Use W=450 N, a=35°, us1=0.4, Hs2=0.75 and P=115 N.

4) Calculations for the red dog food can rolling down the slope in the Rube Goldberg design are as follows (we will name it Step 1): Step 1 (calculations are given): Coefficient of friction → μ = 0.14 Mass of the object → m = 368 gm = 0.368kg Initial height of the object (red can on top of books) → h=8.89, cm = 0.0889 m Slope of the file folder → 0 = 14° Travelling Distance by the object = 11.5 inch = 0.292 m And length that the object will travel = h/sin 0 = 0.0889/ sin14° = 0.367 m So, the radius of the object → R=0.367 -0.292 = 0.075 m Initial Velocity of red can → u = 0 Velocity and Force Calculations for Step 1: -From total mechanical energy conservation: → Initial mechanical energy = final mechanical energy → mg - In case of pure rolling, the velocity of the center of mass: → V = Ro = 0.075 × 14.28 1.07 m/s. -Hence the change in force acting on the object for the travel: →F=mgsine = 0.368 × 9.81 × sin14° =0.89 N Step 2: The Selective Step (Step 2) in this design and for the…
