A straw has an outer diameter of 14 mm, inner diameter of 11 mm, and length of 21 cm. It is made of glass with a Young's modulus of 68 GPa and tensile strength of 7 MPa. a. What is the effective spring constant of the straw with respect to elongation in N/m? b. When you hold either end you can stretch the straw with up to 90 N. How much does the straw elongate in mm? c. By how much can you extend the length of the straw before it breaks?

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (Ï = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
