is recreating rolling The large stone columns by animal power and pivot points cut into the center of each of the column. The friction in each pivot point plus the rolling resistance creates a resisting couple of 300 ft*lb (like a rusty bearing). The yoke angle B = 10⁰. a) Determine how many horses (i.e. horsepower https://en.wikipedia.org/wiki/Horsepower) they need to move a 4600-lb column that is 10 ft long and 2 ft in diameter up a 0 = 5° slope from rest to 3 miles per hour after 15 feet of travel. b) Determine how many horses they need to maintain a constant speed of 3 mph up the slope. Round your answers up to the nearest integer. A fraction of horse doesn't pull very well. Assume the column rolls without slipping.

Question
Problem 1
The SERO CHIENS C
is recreating rolling
large stone columns by animal power and pivot points cut
into the center of each of the column. The friction in each
pivot point plus the rolling resistance creates a resisting
couple of 300 ft*lb (like a rusty bearing).
The yoke angle B = 10°.
a) Determine how many horses (i.e. horsepower
https://en.wikipedia.org/wiki/Horsepower)
they need
to move a 4600-lb column that is 10 ft long and 2 ft
in diameter up a 0 = 5° slope from rest to 3 miles per
hour after 15 feet of travel.
b) Determine how many horses they need to maintain a constant speed of 3 mph up the slope.
Round your answers up to the nearest integer. A fraction of horse doesn't pull very well.
Assume the column rolls without slipping.
