A particle is acted on by two torques about the origin: τ→1 has a magnitude of 8 N·m and is directed in the positive direction o
lyudmila [28]

To give solution to the exercise we must use the concepts of Torque, Vector magnitude and vector direction of the forces.

For the given problem we have to

T_i = 8Nm

T_j = -8.9Nm

In this way the torque acting on the particle as a function of distance and time is,

\tau = \frac{dL}{dt} = 8\hat{i}-8.9\hat{j}

The net torque acting on the particle is

\tau_{net} = \sqrt{T_i^2+T_j^2}

\tau_{net} = \sqrt{(8)^2+(-8.9)^2}

\tau_{net} = 11.967Nm

PART B) The direction of the torque is given by,

tan\theta = \frac{y}{x}

\theta = tan^{-1}\frac{y}{x}

\theta = tan^{-1}(\frac{-8.9}{8})

\theta = -48.04\°

Therefore the torque direction is 48.04° below the x axis.

Given that coal used by electric power plants has a heating value of 27.5 million btus metric ton (25 million btus per ton), det
fredd [130]

Answer:

• 36.4 kg of coal.

• 80 pounds of coal.

Explanation:

Using proportionality constant,

Mass of coal = 1,000,000/27,500,000 btus/metric ton

= 0.0364 metric tons of coal

Mass of coal = 1,000,000/25,000,000 btus/ton

= 0.04 tons of coal.

Converting metric tons to kilogram,

1 metric ton = 1000kg,

0.0364 metric ton;

= 36.4 kg of coal.

Converting tons to pounds,

1 ton = 2000 pounds,

0.04 metric ton;

= 80 pounds of coal.
