Question
Transcribed Image Text:A governor of the Proell type has each
arm 250 mm long. The pivots of the
upper and lower arms are 25 mm from
the axis. The central load acting on the
sleeve has a mass of 25 kg and the
each rotating ball has a mass of 3.2 kg.
When the governor sleeve is in mid-
position, the extension link of the
lower arm is vertical and the radius of
the path of rotation of the masses is
175 mm. The vertical height of the
governor is 200 mm. If the governor
speed is 160 r. p.m. when in mid-
position, find: 1. length of the
extension link; and 2. tension in the
upper arm.
