Known facts:
A line shaft rotating at 250 rpm, a grinder shaft that turns at 1200 rpm diameter of grinder pulley is 5 inches.

1. Proportion equation
350/1200 = 5/x

2. Cross multiply
1200*5=250*x
x=(1200*5)/250 = (24*50*5)/(5*50) = 24
The big wheel diameter is 24 inches

8y-2d=0 5y+4d=26 1/4

Answer:

y = 1

d = 4

Step-by-step explanation:

8y - 2d = 0 ---------------(I)

5y + 4d = 26 1/4

5y + 4d = 105/4 ------------------(II)

(I)*2 16y - 4d = 0

(II) 5y + 4d = 105/4 {add (I) &(II)}

21y = 105/4

$y = \frac{105}{5*21}\\\\y=\frac{105}{105}\\\\y = 1$

Substitute y =1 in equation (I)

8*1 - 2d = 0

8 - 2d = 0

-2d = -8

d = -8/-2

d = 4
