A) 400 rpm
B) 280 rpm
C) 800 rpm
D) 535 rpm
Correct Answer: B
Solution :
\[{{\phi }^{8\,-\,1}}=\frac{1120}{100}\phi =11.2\] \[\phi =1.412\] \[{{N}_{1}}=100\,rpm,\] \[{{N}_{2}}=100\times 1.412\] \[=\text{ }0.141.2\text{ }rpm\] \[{{N}_{3}}=141.2\times 1.412=200\] \[{{N}_{4}}=280\,rpm\]You need to login to perform this action.
