Type the correct answer in the box. Spell all words correctly. Ronny wants to calculate the mechanical advantage. He needs to determine the length of the effort arm and the length of the load arm. How can he find the length of the effort arm? The length of the effort arm is the distance between the _____ and the point at which effort is applied.
Answer:
Fulcrum
Explanation:
The length of the effort arm is the distance between the Fulcrum and the point at which effort is applied.
Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys. Despite changing the forces that are applied the conservation of energy is still true and the output energy is still equal to the input energy. Typically the mechanical advantage is expressed in ideal terms, where there is no losses in energy between the input and output times, also known as 100% efficient systems.
By conservation of energy:
Fi×di=Fo×do
Acme Logistics provides "Less than truck load" (LTL) services throughout the U.S. They have several hubs where they use cross-docking to move goods from one trailer to another. Acme built its last hub 10 years ago, and it had 36 dock doors. The cost index at that time was 140, and the total cost was $6 million. Acme plans a new hub that will have 48 dock doors. The cost index now is 195, and Acme will use a capacity factor of 0.82. What is the estimated cost of the new hub?
Answer:
The answer is "$10.12 million"
Explanation:
To find the price of the 36 dock doors only at the current rate, just use the cost index.
[tex]C_n=C_k \times (\frac{I_n}{I_k})\\\\[/tex]
[tex]= 6 \times \frac{195}{140} \\\\= \$ \ 8 \ million[/tex]
Its current cost of 36 dock doors is, thus,[tex]\$ \ 8 \ million[/tex]. To calculate the price for 48 dock doors, just use the second formula now:
[tex]\to (\frac{C_A}{C_B})=(\frac{S_A}{S_B})^{X}\\\\\to C_A=C_B \times (\frac{S_A}{S_B})^{X}\\\\[/tex]
[tex]=8 \times (\frac{48}{36})^{0.82}\\\\= \$ 10.12 \ million[/tex]
