please see this,,, sir/madam,,, why is it in problem 206
unit mass of 7850kg/m3 is not used to solve for the deformation due to weight directly to the formula,Deformation= (unit mass)(gravity)(L^2)/(2)(E) or solve for the force which is equal to the weight = (unit mass)(g)(AxL) which is equal to (7850kg/m3)(9.81m/s^2)(300x10^-3m^2)(150m)[my understanding] which the answer unit is (kg-m)/s^2 that is also equal to newton
P= 7850(1/1000)3(9.81)[300(150)(1000)] which i do not know where (1/1000)^3 came from and also the multiplier 1000 and where has 1x10^-3 for the milli go?
uhm... if i where to use my solution for the deformation,,, what comes as answer was different from the answer provided in 206.
which i guess is quite wrong or my knowledge with the problem is lacking
please reply ,,,, i really want to know why.
