Question
1. The clevis-end turnbuckle shown is subjected to a tensile force of T-1 kip. Determine a. the average normal stress in each leg of the clevis. b. the average transverse shear stress on Clevis the ½” diameter clevis pin. the average "pull out shear" on the clevis threads an estimated ranking of relative stress (from highest to lowest) in the Clevis Turnbuckle c. in d. i. Top View threaded rod body clevis threaded rod thread roots Threaded Rod ii. iii. turnbuckle thread roots iv. turnbuckle legs V. clevis legs vi. clevis legs at pin hole Side Vien Drawn to ½ Scale Vil. clevis pin Notes: Assume that the loads are symmetrical on each leg of the clevis and turnbuckle. To get dimensions for area calculations print out the figure and, using the clevis pin diameter as a reference, use a ruler to scale other required dimensions to the nearest 1/16th of an inch. Present your answer to part d above as a list (the one above is NOT necessarily in the correct order) followed by a brief description of why you chose to order the cross sections as you did.Explanation / Answer
Estimated ranking of the clevis-end turnbuckle subjected to stress from highest to lowest is
1.clevis pin -since this part subjected to more intial tensile stress.
generally used as locknuts for locking two devices and making them work together.
2.clevis legs at pin hole-the part through clevis pins passes and makes it stressed.
3.clevis legs -since they are pinholed they bear clevis pins and bear thel oad acting on it.
4.clevis threaded rod thread roots bears next largest stress acting on the component.
5.Threaded rod body bears maximum possible load to support the component bearing the load.
6.Turnbukle thread roots used to fix the threaded rod body bears less stress compared to clevis threade rod.
7.Turnbuckle legs through which the threaded rod pases back and forth is used for assemblie purpose bears less stress.
