Question
Answer the following Problems from our reference book: Engineering Fundamentals 1. Convert the information given in the accompanying table from Sl units to U.S. Customary units Convert from SI Units To U.S. Customary Units 120 km/h miles/h and ft/s Bru/h and hp ft 1000 W 100 m 80 kg Ib Ib /f 1000 kg/m 900 N lb 100 kPa Ib,/in? th 9.81 m/s ft/s 2. The angle of twist for a shaft subjected to twisting torque can be expressed by the following equation TL JG where 6 = the angle of twist in radians T- applied torque (N m) L = length of the shaft in meter (m) J = shaft's polar moment of inertia (measure of resistance to twisting) G = shear modulus of the material (N/m?) What is the appropriate unit for J, if the preceding equation is to be homogeneous in units?

3. Calculate the second moment of area of a 2-in-diameter shaft about the x-x and y-y axes, as shown y 4. Determine the natural frequency of a pendulum whose length is 5 m. th 5. Consider the piping system shown in the accompany- ing figure. The speed of water flowing through the 4-in.-diameter section of the piping system is 3 ft/s. What is the volume flow rate of water in the piping sys- tem? Express the volume flow rate in ft'/s, gpm, and L/s. For the case of steady flow of water through the piping system, what is the speed of water in the 3-in.-diameter section of the system? 4 in. 3 ft/s 3 in.
