Part II M1 = 40 kg M2- 32 kg The length of the plank is 3.0 m and it has a mass of 20.0 kg. How far from the left end of the planlk should the fulcrum (pivot point) be placed to for mechanical equilibrium? Assume that the plank's mass is uniformly distributed and that Mass M2 is 0.3 m from the right end of the plank. the right end of the plank. asured from the left end.

The plank of negligible mass is shown in the figure and is pivoted about the indicated point. Two upwardly directed forces act on the plank. A force of magnitude F1-35.7 N acts at one end of the plank at a distance of x167.3 cm away from the pivot. A second force of magnitude F2=14.9 N acts at the opposite end of the plank at distance of x2 = 27.5 cm from the pivot, what is the size of the net...

A block of mass m1 sits on a block of mass m2. Block m2 rests on a frictionless surface. The coefficient of static friction between block m1and m2 is µ. What is the maximum force F that can be applied to block m2 if block m1 is not to slip across the surface of m2? Express in terms of m1, m2, g, and µ.

Two masses M1=2kg and M2 are attached by a massless cord over a solid pulley wheel of mass M=4kg, and radius R=5cm. Static Friction between the cord and the pulley makes the pulley rotate counter-clockwise when the system is released from rest, M1 accelerates with a magnitude of 3.92 m/s2. a) Draw and label the forces acting on the two blocks, and the pulley. (6 points) b) Find the tension in the cord between the pulley and M1 (6 points)...

Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest. The inclined plane has coefficients of static and kinetic friction μs and μk respectively where the angle θ is small enough that mass M1 , would remain at rest due to static friction if...
