1. Imagine the plumb bob as a perfect cone, compute for the volume of steel needed to make thecone if the dimension are a diameter of 60 mm and a height of 40 mm.
The height of a cone shaped tank for liquid storage in a chemical factory is 9 ft with a diameter of14 ft. a) what is the volume of liquid the tank can hold in cubic feet? (5 pts); b) if the storage tankreleases water with a rate of 350 liters per minute, how many minutes will it take for the tank beemptied?
Rigid bar ABC is supported by pin-connected axial member (1) and by a pin connection at C, as shown in the figure. A 5,600-lb
concentrated load is applied to the rigid bar at A. Member (1) is a 3.25-in-wide by 1.00-in-thick rectangular bar made of steel with a
yield strength of oy = 32,000 psi. The pin at C has an ultimate shear strength of oy = 64,000 psi. Assume P = 5,600 Ib, a = 19 in, b=
29 in., c= 12 in., and d = 22 in.
(a) Determine the axial force in member (1) (positive if in tension and negative if in compression).
(b) Determine the factor of safety in member (1) with respect to its yield strength.
(c) Determine the magnitude of the resultant reaction force acting at pin C.
(d) If a minimum factor of safety of FS = 2.7 with respect to the ultimate shear strength is required, determine the minimum diameter
that may be used for the pin at C.
