As we know that,
For point load, deflection = wl^3/48EI and for UDL deflection = 5wl^3/384EI.
So, the ratio is 1.6 i.e 8/5.
For point load, deflection = wl^3/48EI and for UDL deflection = 5wl^3/384EI.
So, the ratio is 1.6 i.e 8/5.

We knw that,
Deflection in sim.
Supp. Beam is = WL3/48 EI,
For UDL 5WL3/ 384 EI
So, right answer is 1.6 or 8 /5.

Ratio of both = 8/5.

Deflection for center load = WL^3/48EI.
Deflection for udl load = 5WL^3/384EI.
Ratio of both load = 8/5.
Deflection for udl load = 5WL^3/384EI.
Ratio of both load = 8/5.

Yes, but according to the question, W = wl which means total load.
Now, W becomes 5wl^3/384EI.
Now, W becomes 5wl^3/384EI.

Ya deflection on UDL beam is (5wl^4)/384EI.

Maximum deflection of a uniform loaded simple beam is (5FL^4)/384EI not (5FL^3)/384EI.

Point load WL^3/3EI.
UDL 5WL^3/384EI.
RATIO IS 8/5.
UDL 5WL^3/384EI.
RATIO IS 8/5.

At point load = WL^3/48EI.
At uniformly distributed = 5WL^3/384EI, So.
Ratio is= 8/5.
At uniformly distributed = 5WL^3/384EI, So.
Ratio is= 8/5.
