Each of the steel links AB and CD is connected to a support and to
member BCE by 25-mm-diameter steel pins acting in single shear.
Knowing that the ultimate shearing stress is 210 MPa for the steel
used in the pins and that the ultimate normal stress is 490 MPa for
the steel used in the links, determine the allowable load P if an
overall factor of safety of 3.0 is desired. (Note that the links are not
reinforced around the pin holes.)
3. A 15% magnesium chloride solution is flowing through a 5-nom sch 40 commercial steel pipe
at a rate of 325,000 lbm/h. The average temperature of the magnesium chloride solution as it flows
through the pipe is 10°F. Determine the convective heat transfer coefficient inside the pipe.
2. Jojoba oil is flowing through a ¾-nom stainless steel pipe at a flow rate of 1,850 lbm/h. After
the velocity profile in the pipe is fully developed, the oil enters a heater, as shown in Figure P5.7.
The length of the heater section is 5 ft. The properties of the jojoba oil at the average temperature
in the heater section are given in Table P5.7. Determine the convective heat transfer coefficient

Shaft 1 is the input, rotating at 1800 rpm and receiving power directly from an electric motor through a flexible coupling. Shaft 2 rotates at 900 rpm. Shaft 3 is the output, rotating at 300 rpm. A chain sprocket is mounted on the output shaft as shown and delivers the power upward. The data for the gears are given in Table 12-5. Each gear has a 1412° normal pressure angle and a 45° helix angle. The combinations of left- and right-hand helixes are arranged so that the axial forces oppose each other on shaft 2 as shown.
