Last time we determined the value for one of the key variables in the Euler-Eytelwein Formula known as the angle of wrap. To do so we worked with the relationship between the two tensions present in our example pulley-belt assembly, T. Today we’ll use physics to solve for _{2}T and arrive at _{2}the which enables us to compute the amount of Mechanical Power Formula,present in our power , a common engineering task.pulley and belt assembly To start things off let’s reintroduce the equation which defines the relationship between our two tensions, the Euler-Eytelwein Formula, with the value for
Before we can calculate T. But before we can do that we need to discuss the concept of _{2}power.
Generally speaking, power,
Now let’s make equation (2) specific to our situation by converting terms into those which apply to F, applied over a distance, d. Looking at things that way equation (2) becomes,
In equation (3) distance divided by time, or “
Equation (4) contains variables that will enable us to determine the amount of P, being transmitted in our .pulley and belt assembly The force, F, is the difference between the belt’s tight side tension, T, and loose side tension, _{1}T. Which brings us to our next equation, put in terms of these two tensions,_{2}
V (5) Equation (5) is known as the .pulley and belt assemblies The variable
