M, M2 R friction The figure above illustrates a system comprising a rigid support structure having a cross-sectional shape of a right-triangle. The angle at the top is equal 90° and the angle on the lower-left is 0. The bottom side (hypotenuse) is horizontal and the two remaining sides serve as left-side and right-side inclined planes. A 1ª block having mass Mi is positioned on the left-side inclined plane and a 2nd block having mass M2 is positioned on the right-side inclined plane. An ideal rope under tension T extends from the 1* block parallel to the left-side plane toward an ideal fixed-axis pulley located at the top of the structure. The rope extends over the pulley and then continues parallel to the right-side plane to the 2nd block. The right-side plane is friction-less but the left-side plane has a coefficient of static friction (S). All parts of this system are remaining at rest. a) Provide a list of the magnitudes of the forces acting on the 1t block, using symbolic names or…

Problem 6: The man in Fig. (a) is trying to move a packing crate across the floor by applying a horizontal force P. The center of gravity of the 300-N crate is located at its geometric center. Does the crate move if P=75 N? The coefficient of static friction between the crate and the floor is 0.3. Calculate the force P required to cause tipping of the packing crate in Problem 6. Also determine the minimum coefficient of static friction that permits tipping. Also, Draw the FBD.
