As an intern at an engineering firm, you are asked to measure the moment of inertia of a large wheel for rotation about an axis

klio [65]

Hi there!

We can begin by finding the acceleration of the block.

Use the kinematic equation:

$d = v_0t + \frac{1}{2}at^2$

The block starts from rest, so:

$d = \frac{1}{2}at^2\\\\12 = \frac{1}{2}a(4^2)\\\\\frac{24}{16} = a = 1.5 m/s^2$

Now, we can do a summation of forces of the block using Newton's Second Law:

$F = ma = m_bg - T$

mb = mass of the block

T = tension of string

Solve for tension:

$T = m_bg - ma = 8.2(9.8) - 8.2(1.5) = 68.06 N$

Now, we can do a summation of torques for the wheel:

$\Sigma \tau = rF\\\\\Sigma\tau = rT$

Rewrite:

$I\alpha = rT$

We solved that the linear acceleration is 1.5 m/s², so we can solve for the angular acceleration using the following:

$\alpha = a/r\\\\\alpha = 1.5/.42= 3.57 rad/sec^2$

Now, plug in the values into the equation:

$I(3.57) = (0.42)(68.06)\\\\I = (0.42)(68.06)/(3.57) = \boxed{8.00 kgm^2}$

How much time will it take a 75w ceiling fan to convert 1500j of electrical energy into mechanical and thermal energy?

-Dominant- [34]

20h

Explanation:

Given parameters:

Electrical power = 75W

Electrical energy = 1500J

Unknown:

Time taken = ?

Solution:

Electrical power is the amount of voltage that drives current.

P = IV

Electrical energy is the voltage that drives a current per unit of time

E = IVt

E = Pt

Since time is the unknown, we can make it subject of the formula;

t = $\frac{E }{P}$ = $\frac{1500}{75}$ = 20h
