Using $$F=325\mathrm{lbf}$$, design the lever arm CD shown in the following figure by specifying a suitable size. Assume the material to be used in the design is 1035 CD. a. Determine the diameter of the bar currently shown as 1", using the Distortion Energy Method. Take the design factor to be 1 . b. Determine the force that could be applied to the bar, if the diameter calculated in part (b) was increased by $$10\%$$. c. Using the ratio of Fmax to $$F$$ as the updated design factor, what is the maximum allowable stress before yielding in kpsi? Ans. The diameter for a design factor, $$n_d$$, of 1 is in. The maximum force that could be applied is Ib. The maximum allowable stress before yielding is kpsi.
