An external tensile force (F) is applied to the femur. Assume the applied force (F) coincides with the centroid of the cross sectional area. Using the axes below, sketch how the internal normal stress varies along the y-axis at the midpoint of the femur. In your sketch, indicate the values of the normal stress at the centroid (y = 0), y = r, and y = -r.

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
