Homework: Determine the angular displacement of the crushing ram. Crank is rotated 70 degrees going CW....
The following figure shows a rock crushing mechanism. Determine the angular displacement of the crushing ram if the crank is rotated clockwise by 25° from the starting position (shown in the figure). Write your result in degrees and in absolute value 360 mm Crushing ram Crank T 60 mm 75° 180 mm 420 mm
atic di the number of degrees of freedom. agram of the rock-crushing mechanism shown and determine ← 230 mm 230 mm 60m 25 Crank 180m 250 mm 320 mm Crushing Tam 130 mm 250 mm
10 Marks Question Five A cam drives a flat-faced follower. It is designed for.a zero lift from 0 to 70 degrees and for a harmonic in the rise from 70 to 150 degrees. It then dwells at 40 mm lift for cam angles from 150 deg to 250 deg. Followed by a return with a uniform-motion follower displacement from 250 to 360 degrees. If the cam angular velocity is constant ot 1000 rpm, determine 40.0 70 100 150 200 250...
