A pair of bevel gears has the velocity ratio equal to
(1.5). The driven gear
has 20 teeth of (15.71) circular pitch and runs at 600 r.p.m.
Calculate accurately
all dimensions and make working drawing showing the gears engaged.
The shaft
diameters of driver and driven gears are 30 mm and 25 mm
respectively.
Additionally, make the hub diameter equal to (1.7) from the shaft
diameter.
Backing for driver and driven are 28 mm and 22 mm respectively
Velocity Racing School is a company that trains people to drive
their sports cars on a track. They are under contract with
Thunderhill Raceway to train drivers on that track. They are paid
$500 per student, and at the end of the month, they receive an
additional $100 per student if 80% or more of the students rate the
instructors as ‘excellent’. They are paid on the
10th
of the following month. They make adjusting entries both mid and
end...
A gear has an angular velocity equal to 20 rad/s initially, but
it speeds up to 40 rad/s in 5.0 seconds, while experiencing angular
acceleration that is constant. Compute the number of turns the gear
has undergone during those 5.0 seconds?
