Question

Mechanisms The figure below shows the drive mechanism of a cold saw. The frame holding the blade moves forward and back after a slide rail. The power is transmitted from the gear wheel via the drive arm AB. The flywheel rotates at a constant speed of 60 rpm. Counterclockwise. When the flywheel is in the position = 45° the following should be determined: a) Blade speed b) Angular velocity of the drive arm AB B 450mm 100m 100m A

Answer 1

Solution B 0:45, -100 min 4 somn 100 mm flywhee Given; flywheel speed - 608pm. In above figure slides crank mechanism is used. - B9 A here, at a slider (Blade) AB » Drive orm. length: 4.50mm 1 fixed link, 3 Driving arm 2->coanka 4 slides (Blade)
we consider  length ob is 100mm.

(a) Blade speed is equal to 626.4482 mm/sec.

(b) Angular velocity of driven arm AB 10.18977 rpm in clock wise direction.
