The ideal (not idea) mechanical advantage is 30/4 = 7.5
It may be possible to generalise results to other integer values.
fixed perimeter is the perimeter being fixed
the fixed cost can be negative if and only if the basis of calculating the fixed cost is not realistic or representative such as the high low method that relies on extreme values only to ascertain the fixed and variable cost.
In that use the term "Fixed" means a known quantity or a specific amount. If you have a "fixed amount of cash" it means you know there is a specific amount available and no more.
scale???????
It is 30/4 = 7.5
' 1 ' is.
Mechanical advantage of a fixed pulley
yes
A fixed pulley does NOT multiply the effort force or have a mechanical advantage. It only changes the direction of the effort force. A free pulley multiplies the effort by two. this means the free pulley has a mechanical advantage of 2.information from:www.mhscience02.com
Single fixed pulley
A single fixed pulley (:
no it does not,it has no mechanical advantage whatsoever. It is just an advantage because it goes in the opposite direction in which you pull.
Thew pulley changes the direction of the effort force.
Because it has a low input force
Fixed Pulley!!
The mechanical advantage would be 1 because the force required to life the mass of an object becomes 1/2 the original weight of the object.
