Apply the appropriate mathematical operation to solve this fulcrum problem.
ale4655 [162]
<h2>Hello!</h2>

The answer is:

The second distance (distance_{2}) is equal to 7.5 feet.

<h2>Why?</h2>

Since we are given two forces acting at distance, torque will be created. We are given two forces and one distance, so, to calculate the other distance required to balance the system (solve this fulcrum problem), we need to write the following equation:

Torque_{1}=Torque_{2}

Where,

Torque=F*Distance

We are given,

Force_{1}=Weight_{1}=150lb\\Force_{2}=Weight_{2}=30lb\\distance_{1}=15ft\\

So, substituting and calculating, we have:

Torque_{1}=Torque_{2}

Weight_{1}*distance_{1}=Weight_{2}*distance_{2}

150lb*15ft=300lb*distance_{2}

distance_{2}=\frac{150lb*15ft}{300lb}=7.5ft

Hence, the second distance (distance_{2}) is equal to 7.5 feet.

It's a logical solution since the second force is twice the first force and it means that the second distance must be equal to half the first distance in order to maintain the equilibrium condition.

Have a nice day!

One end of a ramp is raised to the back of a truck 5 feet above the ground. 1 point
sveta [45]

Answer:

38.7°

Step-by-step explanation:

You are basically looking at a triangle with a 90° angle (check picture).

Since we are looking for the ramp's angle and are given the length of the opposite and the hypothenuse, we have to solve the following equation:

sin (\alpha) = opposite / hypothenuse= 5 ft/8ft

which is equivalent to

\alpha = sin^{-1}(5/8)\approx 38.7\deg

Novay_Z [31]

Answer: The answer is A, 40.

2 x 2 = 4 + 4 x 4 = 16

4 + 16

= 20 + 2 x 40

20 + 80 = 100

(x = 40)
