Question

1 Que 1.2) 1) A vehicle needs to run continuously at 60 kmph and should have a peak torque of 150 Nm. A motor gives peak torque of 25 NM at 3000 rpm. 7) If the gear ratio is given by the expression: "n:1", compute the value of 'n'
​

Answer 1

Answer:

6

Explanation:

gear ratio =out put torque/ input torque

Answer 2

Answer:

6

Explanation:

The gear ratio expresses the ratio of the output Power to the input power

$P_{out}= \tau_{out}\times 2\pi f_{}\\\\P_{in}= \tau_{in}\times 2\pi f_{}\\\\\implies GearRatio =\frac{\tau_{out} }{\tau_{in} }$

Given that:

Gear ratio is n:1 ,

$\tau_{out}= 150 Nm\\\tau_{in} =25 Nm$

⇒ n = 150/25 = 6. Gear ratio will be 6 : 1.
