A box that weighs 200N is sitting on an inclined ramp. The weight is assumed to act at the centroid of the box. A rope is attached to the box and passes over a stationary drum. Both of these surfaces have static friction coefficients as shown in the diagram. A) What is the minimum force, P, is required to prevent the box from moving down the ramp? B) If the rope were to be cut, would the box slip or tip down the ramp or would it stay in equilibrium? Support your decision with all appropriate diagrams/work/equations necessary.

Machine elements are subjected to varieties of loads, some components are subjected to static loads, while some machine components are subjected to fluctuating loads, whose load magnitude tends to fluctuate. The components of a machine, when rotating at …

Stress is defined as force per unit area. When there is localization of huge stresses in mechanical components, due to irregularities present in components and sudden changes in cross-section is known as stress concentration. For example, groves, keyways…
