Draw the acceleration polygon. Show Transcribed Text C U From the drawn polygon, find angular acceleration of link 2 (link BC) and the translating acceleration of the block C.

Problem 3 The gear system shown below has a motor supplying 38 kW at 340 rpm to gear A. Assume the following information: • Shaft (1) is a solid 45-mm-diameter aluminum [G= 22 GPa] shaft with a length of L₁ = 1230 mm. • Shaft (2) is a solid steel [G = 75 GPa] shaft with a length of L₂ = 700 mm. • Shafts (1) and (2) are connected at flange C, and the bearings shown permit free rotation of the shaft. • Assume NÃ=29 teeth and NB=71 teeth.
