8mm tapes can only be viewed with the aid of an 8mm player. One's best bet to watch 8mm tapes in this case is to purchase another 8mm player that is not broken.

Calculate cross sectional area of 10mm bar amd 8mm bar, then divide them and you will get the no. of bars. For Eg. - Area of 10mm bar = 78.53 sq.mm Area of 8mm bar = 50.26 sq.mm No. of 8mm bars in replacement for 10mm bar = 1.562 bars [ theoritical] In practical u'll provide 2-8mm bars.

Rolling margin is percentage of diviation in Sectional weight of Reinforcement steel allowable as per IS codes.Reinforcement steel is extruded from a mould which is made for a particular size e.g 8mm Dia.When the mould is brand new,the sectional weight of 8mm steel extruded through mould would exact as per IS standard of lower than that.i.e. 0.395Kg per Metre or lessor.Mould gets little bigger after certain period of time or after certain quantity of production is taken from a particular mould.Now same 8mm dia bars extruded from the same mould will have more weight per Metre say 0.400Kg per Metre insted of 0.395 as per IS. That is more mass per Metre/Length is required for same length.This diviation in weight is defined in IS codes for different dia which is as under :- 8mm to 10mm +_ 7% 12mm to 16mm+- 5%. 20mm and above+ -3%. Rolling Margin is calculated as under :- Total Weight of Bars (Dia wise ) / Total Running Metre of Bars = Actual Sectional Weight of bars. Compare sectional weight with Standard IS Weight. Weight as per IS Standard.= Dia X Dia / 162. ----

Rolling Margin is the deviation of actual unit weight to that of Standard unit weight as per IS Standards. Rolling Margin is calculated as : Sectional weight = Weight of Steel Bars dia wise / length of the bars. As per IS Standards unit weight of the Bars is calculated as dia x dia / 162 Rolling Margin is deviation of actual sectional weight to that of IS Standard unit weight. Standard Rolling Margin for different dia reinforcement bars used for construction purposes: 8mm to 10mm +- 7% 12mm to 16mm +- 5% 20mm & Above +- 3%
