Calculate the mechanical advantage if a machine allows you to move a 60 newton rock by only exerting 15 newtons of force.
murzikaleks [220]

Answer:

4 Newtons

Explanation:

  • I think it's 4 because mechanical advantage = output force/input force
  • So, it would be 60/15, which is 4 newtons

the formula relates the time, t, in seconds for a pendulum with the length, l, in feet, to make one full swing back and forth. w
Dovator [93]

This shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.

Given the formula for calculating the length of the pendulum expressed as:

T= 2\pi\sqrt{\frac{L}{32} } where:

L is the length of the pendulum

T is the period of the pendulum

Given the following parameters:

Period T = 2.2 seconds

Substitute the given parameters into the formula will give;

2.2=2\pi \sqrt{\frac{L}{32} }\\ (\frac{22}{6.58} )^2 =\frac{L}{32} \\L=3.5032 \times 32\\L = 3.92.71 feet

So, this shows that the length of a pendulum that makes one full swing in 2.2 seconds is 392.71 feet.

block of mass m sits at rest on a rough inclined ramp that makes an angle with the horizontal. What must be true about normal fo
oee [108]

Answer:

Explanation:

For a body on a ramp with mass m, the forces acting on the body along the vertical component are the weight and the normal reaction.

The weight of the body acts in the negative y direction while the normal reaction acts in the positive y direction

Taking the sum of forces along the y component

Sum Fy = -W+R = ma

Since acceleration is zero

-W+R = m(0)

-W+R = 0

-W = -R

W = R

Hence the Normal reaction force acting on the on the body is equal to normal force
