You use your finger to tighten a 3/4 10 unc screw. what's the circumference of the effort force?

what's the ideal mechanical advantage of the screw?

the input gear has 44 teeth, the ideal gear has 22 teeth, and the output gear has 10 teeth. what's the ratio gear?

if the input gear is spinning at 30 rpm, how fast is the output gear spinning?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
