If you stand on one leg, the load exerted on the hip joint is 2.4 times your body weight. Assuming a simple cylindrical model for a hip implant, with a cross-sectional area of 5.6 cm2, estimate the following: a) The corresponding stress on the hip implant in a 175-lb individual: ………………. [MPa] (0.2)
b) If the hip implant is made of Ti-6Al-4V (120 GPa elastic modulus), what is the strain for the current loading conditions? ………………. (0.1)
c) Complete solution (please show your work on a scrap paper, scan it, and insert the image below) (0.1)

What precautions should you take to prevent injuries when dealing with heavy loads?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
