MCQ

An automobile engine develops $100\ kW$ when rotating at a speed of $1800\ rev/min$. What torque does it deliver .......... $N-m$

A
$350$
B
$440$
✓
$531$
D
$628$

✓

Answer

Correct option: C.

$531$

c
$P = \tau \omega $

$⇒$ $\tau = \frac{{100 \times {{10}^3}}}{{2\pi \,\frac{{1800}}{{60}}}} $

$= 531\,N{\rm{ - }}m$

A ball is thrown from the location $\left(x_0, y_0\right)=(0,0)$ of a horizontal playground with an initial speed $v_0$ at an angle $\theta_0$ from the $+x$-direction. The ball is to be hit by a stone, which is thrown at the same time from the location $\left(x_1, y_1\right)=(L, 0)$. The stone is thrown at an angle $\left(180-\theta_1\right)$ from the $+x$-direction with a suitable initial speed. For a fixed $v_0$, when $\left(\theta_0, \theta_1\right)=\left(45^{\circ}, 45^{\circ}\right)$, the stone hits the ball after time $T_1$, and when $\left(\theta_0, \theta_1\right)=\left(60^{\circ}, 30^{\circ}\right)$, it hits the ball after time $T_2$. In such a case, $\left(T_1 / T_2\right)^2$ is. . . . .
