2. Greg wants to have $50 000. He will invest S20 000 today in investment certificates that pay 8% nominal interest, compounded quarterly. How long will it take him to reach his goal?
The truss ABCD shown in the figure is loaded by a vertical force P at joint Band by a horizontal force P at joint C. The axial rigidity of every member is EA. Determine the vertical displacement δc of joint C. (Hint: Add a vertical load Q at joint..
Refrigerant 134a flows at steady state through a horizontal tube having an inside diameter of .05 m. The refrigerant enters the tube with a quality of .1, temperature of 36 C, and velocity of 10 m/s. The refrigerant exits the tube at 9 bar as a satur..
The maximum shear strain at a point in a thin elastic plate is given as gamma (max) = 450(mu). it is also known that the sum of the normal stresses on two perpendicular planes passing through the point is 30 mpa. Determine the magnitude of the princi..
