PROBLEM 2. A block of mass weighing 200 kg is being pulled upward along an inclined surface. The angle of the surface with respect to the horizontal axis is 15°. The force pulling the block is equivalent to 600 N and is inclined 8° upward with respect to the axis of the inclined surface. a) Determine the component of the pulling force in the horizontal axis. b) Determine the component of the pulling force in the axis perpendicular to the inclined surface. c) Determine the component of the self-weight of the crate in the axis parallel to the line of action of the pulling force.

Solve for the force P required to imprend motion in the following situation: 1. If force applied to block horizontally. 2. If force applied to block downward at 30° with the horizontal. 3. What should be the minimum force P and its angle from the horizontal is required to start motion?

A horizontal force P acts on the top of the 30 N block having a width of 25 cm and a height of 50 cm. If the coefficient of friction between the block and the plane is 0.33. a. What is the value of P for motion to impend? b. Is the motion will impend due to overturning?

Using Virtual work equation, determine the angle a° so that the deflection of the point C is in the same direction as the load P (Consider only EI the effects of bending due to the load P). Note: A direction of loading such that the resulting deflection is in the same L EI direction as the load is called a principal direction. For a given load on a planar structure, there are two principal directions, perpendicular to each other. L
