ringe System for Injecting Triamcinolone Acetonide into Keloids. J Med Eng. 2016;2016:5162394. doi:10.1155/2016/5162394) (a) Alex exerts a force of 90.5 N using a plunger tip with a diameter of 10.3 mm. What is the pressure that Alex creates in the liquid inside the syringe? (b) Tyler can only exert a force of 58.7 N. If they want to inject fluid with the same pressure as Alex, what size should the plunger in their syringe be? 17 ft 10 ft 2. The Beloit dam is 360 feet long. It is 17 feet tall (from the streambed to the top of the dam). The minimum water height of the lower pool is 10 feet. (a) What is the force exerted on the dam by the water in the upper pool? (b) What is the force exerted on the dam by the water of the lower pool? (c) What is the net force on the dam? (d) Do you need to consider the atmospheric pressure in your calculation? Why or why not?
