I am having trouble finding the applied force when i have the mass , maximum value of static friction and coefficient of static friction µ.

Could you quote the exact question from your homework or prac work? So we can understand what this is about.

There is none . I have to fill in the chart by preforming experiments

Where did the values in column E come from?

Did you measure the values in column D?

What is the equation this experiment is going to confirm?

it has to deal with Forces and Friction

i did the mass with 6 trials , each different amount in the masses

and to get the coefficient i used Fmax to find the coefficient. so i put Fmax / Fpress which for trial 1 was 1/ 9.8 because Fpress=mg=9.8m

I don't think you have correctly explained where those figures in column E came from. You seem to have invented them. I believe each should be a calculated value for μ based on the data to its left.

The numbers in column C will be, I think, those in column B but each multiplied by 9.8
