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:

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

Answer:

Explanation:

The application of the breaks by stepping on the break pedal moves the pedal pushrod and plunger forward within the diaphragm plate, bringing about the contact between the vacuum port seal and the vacuum valve that closes the vacuum port and the passage that connects the left and right chambers such that the pressure in one chamber and te vacuum in the other chamber are held steady.

Cloud [144]

Answer:

a. 2x/3

b. 8

Explanation:

fundamental period can be defined to mean that at after every period of 2π radians or 360° the value of graph is repeated. For such functions the fundamental period is the period after which they repeat themselves.

It van also be looked as The fundamental period of cos(θ) is 2π. That is (for example) cos(0) to cos(2π) represents one full period.
