Pertaining to simple machines and levers what changes when the fulcrum position is modified?

Inessa [10]

Explanation :

There are many types of simple machines i.e. lever, wedge, pulley, wheel and axle etc.

Fulcrum is the pivot point about which the lever turns. When the position of the fulcrum is shifted, the position of effort changes.

There are three classes of the lever as class 1, class 2 and class 3.

Class 1 includes seesaws and scissors.

class 2 includes wheelbarrow

class 3 includes tongs and tweezers.

If Phoenix, Arizona, experiences a cool, wet day in June, does that mean the regions climate is changing?

It doesn't mean that the climate is changing, it is probably just the morning dew.

A Ferris wheel on a California pier is 27 m high and rotates once every 32 seconds in the counterclockwise direction. When the w

Leto [7]

A) 140 degrees

First of all, we need to find the angular velocity of the Ferris wheel. We know that its period is

T = 32 s

So the angular velocity is

$\omega=\frac{2\pi}{T}=\frac{2\pi}{32 s}=0.20 rad/s$

Assuming the wheel is moving at constant angular velocity, we can now calculate the angular displacement with respect to the initial position:

$\theta= \omega t$

and substituting t = 75 seconds, we find

$\theta= (0.20 rad/s)(75 s)=15 rad$

In degrees, it is

$15 rad: x = 2\pi rad : 360^{\circ}\\
x=\frac{(15 rad)(360^{\circ})}{2\pi}=860^{\circ} = 140^{\circ}$

So, the new position is 140 degrees from the initial position at the top.

B) 2.7 m/s

The tangential speed, v, of a point at the egde of the wheel is given by

$v=\omega r$

where we have

$\omega=0.20 rad/s$

r = d/2 = (27 m)/2=13.5 m is the radius of the wheel

Substituting into the equation, we find

$v=(0.20 rad/s)(13.5 m)=2.7 m/s$
