Given: Data in Figure 7–28. Input sprocket speed = 1400 rpm
a. Pitch diameters: From Table 7–4,
P32-8MGT-30 sprocket: 32 teeth; Pitch diameter = 3.208 in
P80-8MGT-30 sprocket: 80 teeth; Pitch diameter = 8.020 in
b. Velocity ratio: Using Equation (7–4)  in Section 7–2,

V R=\frac{n_{\text {driving }}}{n_{\text {driven }}}=\frac{N_{\text {driven }}}{N_{\text {driving }}}=\frac{80}{32}=2.50
Driven speed of the driven sprocket:
n_{\text {driven }}=\frac{n_{\text {driving }}}{V R}=\frac{1400 \mathrm{rpm}}{2.5}=560 \mathrm{rpm}
c. Belt speed: Using Equation (7-3) in Section 7-2,
v_{\text {bell }}=\frac{P D_{\text {driving }}}{2} n_{\text {driving }}=\frac{3.208 \mathrm{in}}{2} \cdot 1400 \frac{\mathrm{rev}}{\mathrm{min}} \cdot \frac{2 \pi \mathrm{rad}}{\mathrm{rev}} \cdot \frac{1.0 \mathrm{ft}}{12 \mathrm{in}}=1175.8 \mathrm{ft} / \mathrm{min}
d. Center distance: From Table 7-7, using 32 and 80 teeth and 1200-8 \mathrm{MGT}-30 belt,
C D=14.61 \mathrm{in}
