can someone help me understand this math. this is for me C programming class but there's no way i can code this if i dont understand the math. Compute the diameter in centimeters of a steel rod, an aluminum rod, and a copper rod, which can withstand a particular compression load. The allowable compression stress of steel, aluminum , and copper is 25000 lbs/m^2, 15000 lbs/m^s, and 20000 lbs/m^2 respectively. area of rod = compression load / allowable compression stress area=(pi)r^2 where diameter=2r

    You just need to understand conceptually what is happening?

    i dont know what numbers im suppose to put on "compression load" to get the area of the rod

    Like what to input for the compression load?

    yes

    The resultant diameter is a result of the compression load

    So, for instance, you want a copper/iron/etc. rod to have a compression load of X what diameter must it have so that that is possible

    So that the compression load is a user input and the diameter is what the program outputs

    oooh okay i understand that part but what type of number does the user input lolol just (1,2,3,4,5....55)?

    or try something like float load; int userchoice;

    no worries you helped xD i just really did not know what compression load is. and if i were to run it, i wouldnt know if the numbers that comes out were right xD
