200-lb block is on top of a 300-lb block and both blocks are tied to a pulley a pulley that is attached to the wall, as shown in the figure. The coefficient of static friction between the two blocks is 0.3 and between the 300 lb block and the floor is 0.4. The coefficient of dynamic friction between all surfaces is 0.25. Disregard the friction at the pulley. Determine the minimum force that must be applied to the 300 lb block in order for it to initiate motion (imminent motion).

The beam shown in Figure 1 supports a distributed live load of 1.5 kN/m, and a single concentrated load of 10 kN. In addition, the dead load is 2.0 kN/m. D is a fixed support, B is a roller support and joint C is a hinge. Determine the followings: (a) the key points for the influence lines for the vertical reactions at B (By) and D (Dy) and moment at D (MD). Fill up Table 1 with your calculated values. (b) sketch the influence lines for the vertical reactions at B (By) and D (Dy) and moment at D (MD). (c) the maximum vertical reaction at B (By) for the given loads. (d) the maximum negative moment at D (MD) for the given loads.
