ISMB refers to Indian Standard Medium Weight Beams, which are used for structural steel construction. ISMC refers to Indian Standard Medium Channels, which are used for support and bracing in structural steel frameworks. The main difference is the shape of the cross-section, with ISMB being a beam and ISMC being a channel.
The unit weight of ISMC 200 is approximately 24.2 kg/m.
The unit weight of channel ISMC 300 is approximately 61.5 kg/m.
The unit weight of channel ISMC 75 is approximately 6.85 kilograms per meter.
The moment of inertia of an ISMB 600 (Indian Standard Medium Weight Beam 600) can be calculated using the formula for moment of inertia of a rectangular section: I = (b*h^3)/12, where b is the breadth of the beam and h is the height. The dimensions for ISMB 600 are typically available from manufacturer specifications or standard engineering handbooks.
The phase difference between two waves is directly proportional to the path difference between them. The phase difference is a measure of how much the wave has shifted along its oscillation cycle, while the path difference is a measure of the spatial separation between two points where the waves are evaluated.
