ECOR 2606 Lab Test #1 v6
A belt runs around two pulleys as shown . The length
L
of the belt can be calculated using the
equations given.
where
A =
an angle (in radians)
R
1
=
radius of larger pulley (in m)
R
2
=
radius of smaller pulley (in m)
C
= distance between pulley centres (in m)
L =
belt length (in m)
Part I (3 marks):
Write a function mfile (belt.m) that, given the radii of the two pulleys and the distance between
their centres, computes and returns
L
.
The formula requires that
R
1 be greater than or equal to
R
2.
Your function should make the necessary adjustments if the two radii given to it are the
"wrong" way around.
Part II (7 marks):
The steps required to solve this part should be placed in a script mfile (script.m).
Assume that one of the pulleys has a radius of 0.1 m and that the other has a radius of 1.5m.
