Two pulleys are run by a common belt. If a 10.8 inch diameter pulley turns at 900 rpm, what is the diameter of the second pulley if it turns at 421 R.P.M.?
Note: Speed is inversely proportional to diameter.
In a crank and slotted lever quick return mechanism, distance between fixed centers is 300mm
and length of driving crank is 180mm. The inclination of slotted bar with vertical extreme
position is
degrees.
Write and draw the following grashof's criterion and kind of grashof's four-bar mechanism such as;
1. Crank-rocker mechanism;
2. Drag link mechanism;
3. Double rocker mechanism;
4. Crossover-position or charge-point mechanism;
5 Triple rocker mechanism (non-grashof).
Use technical Pen for the following:
0.2(light -for linkages and hand writing),
0.4(medium - for joints),
0.6(heavy - for fixed link or frames)
use 2-4-4 template, all caps, italicized.
