Now it''s time to size the conduit. Table 1 in Chapter 9 of the NEC, states the allowable percentage of conductor fill is 40%. You can calculate the total area of the three MV cables using the following equation: Area = 3 x (pi ÷ 4) x d 2 Area = 3 x .785 x 1.60 2 Area = 6.03 sq. in.

The cross section is defined by depths at verticals 1,2,3,4, . . . n. At each vertical the velocities are sampled by current meter to obtain the mean velocity for each subsection. The subsection discharge is then computed for any subsection at vertical x by use of the equation, 4s = u.r [

This is a calculator for computing the correct feeds and speeds (RPM and IPM) for milling machines. It differs from other online calculators because it is an OPTIMIZING calculator -- each parameter has a range from minimum to maximum. The calcuator searches for the best cut (maximizing MRR) while keeping all parameters within the range you specify.

Square Pyramid. The surface area of a square pyramid is comprised of the area of its square base and the area of each of its four triangular faces. Given height h and edge length a, the surface area can be calculated using the following equations: base SA = a 2 lateral SA = 2a√ (a/2)2 + h2 total SA = a 2 + 2a√...

Column critical buckling stress calculator - formula & step by step calculation to find the maximum allowable stress of the vertical column. σ = (π 2 x E)/[(l/r) 2]. Young''s modulus (elasticity) of the column material E in Pa, unsupported length of column l in m & least radius of the column r in m are the key terms of this calculation.

Aug 15, 2011· i am curious what other experienced machinist use to determine an end mill depth of cut. for example i use the 2x longer then 2 square (2x2) rule. that is a end mill sticking out 2 times longer then 1/4 depth of cut. i ordered 1/2" end mill with 1.25" LOC but received 1.625 length of cut. Formula ...

Then we need to find whether the top or the bottom of the section is furthest from the neutral axis. Clearly the bottom of the section is further away with a distance c = 216.29 mm. We now have enough information to find the maximum stress using the bending stress formula above:

The formula now has a "break" on month. In other words, on every row where Month is 1, this expression now means "the total revenue of all month 1s". In every row where Month is 2, it means "the total revenue of all month 2s". As a result, the percentages are not the percentages you expect.

First, determine the size of the surface to be covered. Then, choose the direction in which you want to install the caissons: vertical or diagonal. The calculator will generate the maximum and minimum number of caissons you will need to complete your project. The maximum number will allow you to cover the entire surface, but will require some cutting.
