Determine the force P (magnitude of force P) required to support the 450 N force using the pulley system shown below: P:

p=(18−6x+4y)kPa. Suppose that p1 = 18 kPa, p2 = 27 kPa, p3 = 9 kPa a = 3 mm, b = 2.25 mm. Part 1 Determine the magnitude of the resultant force Part 2 Deteremine the x coordinate of the point where the line of action of the resultant force intersects the plate Part 3 Determine the y coordinate of the point where the line of action of the resultant force intersects the plate.

please answer the following   Pistons are fitted to two cylindrical chambers connected through a horizontal tube to form a hydraulic system. The piston chambers and the connecting tube are filled with an incompressible fluid. The cross-sectional areas of piston 1 and piston 2 are A1 and A2, respectively. A force F1 is exerted on piston 1. Rank the resultant force F2 on piston 2 that results from the combinations of F1, A1, and A2 given from greatest to smallest. If any of the combinations yield the same force, give them the same ranking. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols.) F1 = 6.0 N; A1 = 0.7 m2; and A2 = 1.4 m2 F1 = 3.0 N; A1 = 0.7 m2; and A2 = 0.35 m2 F1 = 3.0 N; A1 = 1.4 m2; and A2 = 2.8 m2 F1 = 6.0 N; A1 = 0.35 m2; and A2 = 1.4 m2 F1 = 6.0 N; A1 = 0.35 m2; and A2 = 0.7 m2 F1 = 3.0 N; A1 = 1.4 m2; and A2 = 0.7 m2
