The weights of the 2 boxes are WA 65 lb and WB 130 lb. The coefficient of static friction between all surfaces is u,-0.15. The two blocks are connected to each other by a cable that loops around a frictionless pulley. What is the largest force F for which equilibrium is maintained. 20°
Two blocks are pushed along a frictionless surface. The static coefficient of friction between the blocks is .70 mm is the maximum force F that can be applied to the lower block (as shown on the diagram) Such that the upper block does not slide
2. 10 Points A student using a horizontal table to measure the static friction coefficient between a block (m -2.0 kg) and the surface of the table. The student connects the block (m) and another mass hanger m2 by a light string that passes over a light frictionless pulley as shown in the figure. Now the student adds m2 slowly and carefully until it just begins to move and recordsm rn2 the maximum total mass at this moment (m2 400g...

Problem#7 Two boxes are connected by a weightless cord running over a very light frictionless pulley as shown in the figure. Box A, of mass 8.0 kg, is initially at rest on the top of the table. The coefficient of kinetie friction between box A and the table is 0.10. Box B has a mass of 15.0kg. and the system begins to move just after it is released. (a Draw the free-body diagrams for each of the boxes, identifyi each...

1. Two boxes are stacked on a frictionless table. M. = 4kg and M, 5kg. The coefficient of friction between the boxes is such that when a 27 N force F is applied to the lower box, the boxes start to slip relative to each other. The system is then restored to rest and force F is removed. A horizontal force F is now applied to the upper box. What is this force's maximum value in order for the two...
