A motor supplies 70 kW at 1500 rpm to the flange A. Shaft (1) is solid with 25 mm diameter and shaft (2) is solid with 40 mm diameter. Both shafts are made of steel (G = 80 GPa). The number of bolts used at flange A is 5 and they are arranged along a circle of 30 mm radius (i. e. R = 30 mm). The bolts are steel having allowable shear stress of 65 MPa . The gear fixed to shaft AB has 100 mm diameter and it is engaged to gear C which has 300 mm diameter. If the bearings at B and D permit free rotation of the shafts, then;

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
