You should attend lecture to get the complete notes Images taken from Halliday/Resnick/Walker, Fundamentals of Physics, 7 th Edition, John Wiley and Sons Inc., by permission. Hints P4. Don’t use A = 77 m 2 (misprint) use A = 77 cm 2 P19. You will have to construct an integral to find the force on the dam due to water pressure in a) Start with: = = dam of face PdA F You will have to construct an integral to find the torque on the dam due to water pressure. Start with: where y is measured downward from the water surface. P25 and 40. Start with a free body diagram of the anchor. = = = dam of face dam of face yPdA ydF τ Hints P53b). The pressure on the water after it exits the hole is P 0 since the water is in contact with air (which is at P 0 ). P89. You will need to start out by applying Bernoulli’s equation to find what speed the water emerges from the small pipe at a height of 9.4 m.
