Concrete by Mindness and Young gives a general rule The ratio of 28-day to seven-day strength lies between 1 3 and 1 7 and generally is less than 1 5 or the seven-day strength is normally between 60% to 75% of the 28-day strength and usually above 65% The cylinder that broke at 1980 psi is 66% of the specified 3000 psi According to Mindness and Young's rule it should meet the specified

This calculator may give you a rough idea of the deflection of metal tubing but it's not accurate enough to do any more than estimate it If the deflection is large enough to permanently bend the tube then all bets are off The steel weights are tweaked for mechanical tubing and will be less accurate for structural tubing The moduli of elasticity used are 29 700 000 psi for steel and
