Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Dwarf Fortress. A group of dwarves made an outpost far from their homeland, "Moria, Middle-Earth". They have set-up the outpost near the river. In order to attract adventurers to their outpost, they constructed an underground tavern below (height h1 = 50m) the river. They dug a tunnel and an artificial cistern. Just above = this cistern (height h2= 10m) is the underground tavern. Using Bernoulli's equation and Fluid dynamics, explain if this plan is going to work or not. Meaning, explain if the water will pour out of the cistern into the tavern. If this plan is not going to work, what will be your suggestions (Dwarves live underground. They refuse to create the tavern on the surface)

Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight leg raising with 10 Ib weights. Compute for the force that the muscle should exert in order to (1) maintain it in the position and (2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm, distance of the weight is 80 cm, and the COM is 45 cm from the joint. Questions: 1. Draw the free body diagram for straight leg raise. 2. What is the muscle responsible for straight leg raise? 3. What is the fulcrum? 4. What is the effort? 5. What is the resistance?
