Unformatted text preview: Rotating Hoist Analysis Problem . Develop a simpliﬁed twodimensional model of the rotating hoist behind the Physics
Building (see attached map). Assume appropriate reactions at the supports and
approximate all important dimensions, angles, etc. needed to analyze the problem. . Assume the loading condition is at its maximum capacity and consider the worst case
scenario for the location of the load. The maximum capacity of the hoist is speciﬁed '
on the wall under the hoist. Remember that T is a symbol of tons (i.e., 1T = 2,000
lbs.). Assume the weight of the Ibeam hoist is approximately 501bs/foot of length. . In the analysis, draw a clear free body diagram of the hoist and state any assumptions
you are making. . Do an engineering estimate of the load carried in the support chains and the reactions
at the base of the I—beam hoist. . Develop the equations of static equilibrium for the hoist, but DO NOT plug in any of
the numerical values (i.e., leave the equations in symbolic form). . Estimate the values of the variables needed in the equilibrium equations and calculate
numerical values for the tension in the support chains and the reactions at the base of
the I—beam hoist. Only one submission per group. All group members will receive the same grade. . Adjustments to the regularly scheduled homework assignment will be made to
provide time for you to complete this analysis. I433”... O _ A/EJS. gw/(a 7Q WE; 550 lbs. “What... 7% Mamwmﬁéogd nge, 5kka 40 +144; ...
