1.In solving problems and examining examples, you probably have noticed some recurring forms:
2. Return to Ex. 17–1 and complete the following.
(a) Find the torque capacity that would put the drive as built at the point of slip, as well as the
initial tension
Fi
.
(b) Find the belt width
b
that exhibits
nf s
=
nd
= 1.1.
(c) For part
b
find the corresponding
F1a
,
Fc
,
Fi
,
F2, power, and
nf s
.
(d
) What have you learned?
3. Take the drive of Prob. 17–5 and double the belt width. Compare
Fc
,
Fi
,
F1a
,
F2 ,
Ha
,
nf s
, and dip.
