Part A - Transmitted power A solid circular rod is used to transmit power from a motor to a machine. The diameter of the rod is

uranmaximum [27]

Answer:

Explanation:

Given that solid circular rod rotates at constant speed and neglecting losses throughout the system, power is calculated as the product of torque and angular speed. That is to say:

$\dot W = T \cdot \omega$

There is a formula that relates torque with shear stress:

$\tau = \frac{T \cdot D}{2 \cdot J}$

Where $J$ is the torsion module, whose formula for a solid circular cross section is:

$J = \frac{\pi \cdot D^{4}}{32}$

The tension module is calculated herein:

$J = 3.835 in^{4}$

Maximum allowed torsion is found by isolating it from shear stress equation:

$T_{max} = \frac{2 \cdot J \cdot \tau_{max}}{D}$

$T_{max} = 31.907 kip \cdot in\\T_{max} = 2.659 kip \cdot ft$

Then, maximum transmissible power is determined directly:

$\dot W = (2.659 kip \cdot ft) \cdot (2)\cdot (\pi) \cdot (170 rpm)\\\dot W \approx 2840.188 \frac{kip \cdot ft}{min} \\\dot W \approx 86.066 h.p.$

ale4655 [162]

Answer:

R = V / I , R = V² / P, R = P / I²

Explanation:

For this exercise let's use ohm's law

V = I R

R = V / I

Electric power is defined by

P = V I

ohm's law

I = V / R

we substitute

P = V (V / R)

P = V² / R

R = V² / P

the third way of calculation

P = (i R) I

P = R I²

R = P / I²
