A machine has a mechanical advantage of 4.5. What force is put out by the machine if the force applied to the machine is 800 N?

Ghella [55]

If the machine's mechanical advantage is 4.5, that means that

Output force = (4.5) x (Input force) .

We know the input force, and we need to find the output force. Rather than wander around the room looking at the floor while our hair smolders, let's try putting the numbers we know into the equation I wrote up there. OK ?

Output force = (4.5) x (Input force)

Output force = (4.5) x (800 N)

Now dooda multiplication:

<em>Output force = 3,600 N</em> .

That's exactly what the question asked for. So we're done !

Two spectators at a soccer game in Montjuic Stadium see, and a moment later hear, the ball being kicked on the playing field. Th

NikAS [45]

Answer:

a) 68.943 m

b) 41.846 m

c) 80.648 m

Explanation:

Given:

Delay in time for spectator A, t₁ = 0.201 s

Delay in time for spectator B, t₂ = 0.122 s

the delay in sound heard is the due to the distance being traveled by the sound from the kicker to the spectator

thus,

a) Distance of the kicker from A,

d₁ = speed of sound × time taken

d₁ = 343 m/s × 0.201 s = 68.943 m

b) Distance of the kicker from B,

d₂ = speed of sound × time taken

d₂ = 343 m/s × 0.122 = 41.846 m

c) Since the angle between the two spectators for the player is 90°

thus, a right angles triangle is formed.

where, the distance between the spectators is the hypotenuses (s) of the so formed triangle

Therefore,

s² = d₁² + d₂²

on substituting the values, we get

s² = 68.943² + 41.846²

or

s² = 6504.22

or

s = √6504.22

or

s = 80.648 m

hence, the distance between the spectators is 80.648 m

A thin-walled, hollow sphere of mass M rolls without slipping down a ramp that is inclined at an angle β to the horizontal. Find

Reil [10]

Answer:

Explanation:

Given

inclination $=\beta$

Assuming radius of sphere is r

Now from Free Body Diagram

$Mg\sin \theta -f_r=Ma$

where $f_r=friction\ force$

$a=acceleration\ of\ system$

Now friction will Provide the Torque

$f_r\times r=I\cdot \alpha$

where $I=moment\ of\ inertia$

$\alpha =angular\ acceleration$

$f_r\times r=\frac{2}{3}Mr^2\times \frac{a}{r}$

in pure rolling $a=\alpha r$

$f_r=\frac{2}{3}Ma$

$mg\sin \beta -\frac{2}{3}Ma=Ma$

$Mg\sin \beta =\frac{5}{3}Ma$

$a=\frac{3g\sin \beta }{5}$
