The value must be a scalar - Mathcad prime 9 3

[mathiasfp]

Hi

Im trying to calculate the bending moment and shear force depending on the distance x along the beam.

I tried making "a" into another matrix but then its either not a scalar or it says the number of rows and collums isnt the same.

I saw a similar problem on here but didnt quite understand the solution.

Please help.

Best regards
Mathias

wow ! ... 20mm deflection in a 4m span !?? but maybe we're just "playing" ... with E and I ?

Yes, E and I are not set to a correct value.

L/200 is not unusual if dead and live load are included in the deflection calculation.

Yeah i usually use the danish national version of the eurocode, it varries but L/400 is normal.
