Describe the relationship between input force, output force,and load force.

1 answer:

5 0

Answer: the relationship between the input force and output force is that, Input Force represents the amount of force that you put into another object (which is considered as the load force) while Output Force represents the force that a specific object has as a result of the input force.

Explanation:

Using a lever as an example, a broom is a lever used to sweep floors, the input force is applied by one of the arm used in sweeping, while the output force is on the other edge of the broom (broom tip)

A Rankine oval is formed by combining a source-sink pair, each having a strength of 36 ft2/s and separated by a distance of 15 f

Rashid [163]

Answer:

0.28 ft

Explanation:

We are given that

Strength=m= $36ft^2/s$

Distance between source and sink=15 ft

Distance between the sink of the source and origin= $a=\frac{15}{2}$ ft

Uniform velocity, U=12 ft/s

We have to find the length of the oval.

Formula to find the half length of the body

$\frac{l}{a}=(\frac{m}{\pi Ua}+1)^{\frac{1}{2}}$

Where a=Distance between sink of source and origin

U=Uniform velocity

m=Strength

l=Half length

Using the formula

$\frac{l}{\frac{15}{2}}=(\frac{36}{\pi\times 12\times \frac{15}{2}}+1)^{\frac{1}{2}}$

$l=\frac{2}{15}(\frac{36}{\pi\times 12\times \frac{15}{2}}+1)^{\frac{1}{2}}$

$l=0.14$

Length of oval= $2l=2(0.14)=0.28 ft$

Where does salt in the ocean come from

Bingel [31]

Answer:

Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.

Two velocity vectors, one is twice of the other, and separated by 90 Degree angle. If their resultant is calculated 90 m/s, what

Artyom0805 [142]

Answer:

Vy = 80.5 [m/s]

Explanation:

In order to solve this problem we must use the Pythagorean theorem.

V = 90 [m/s]

The components are Vx and Vy:

Therefore:

$v=\sqrt{v_{x}^{2} + v_{y}^{2} }$

where:

Vy = 2*Vx ; because one is twice of the other.

$90 = \sqrt{v_{x}^{2} +(2*v_{x})^{2} }\\ 90 =\sqrt{v_{x}^{2}+4*v_{x}^{2}} \\90 =\sqrt{5v_{x}^{2}} \\90=2.23*v_{x} \\v_{x}=40.25[m/s]$

and the bigger vector is:

Vy = 40.25*2

Vy = 80.5 [m/s]

Ymorist [56]

If the cross-section of a wire of fixed length is doubled, the resistance of that wire change into doubled.We know that the total length of the wires will affect the amount of resistance. The longer the wire, the more resistance that there will be so the answer is doubled.
