Use Ftool software for this numerical. Consider the following specifications

for a concrete beam:

$$ Concrete isotropic material

$$ E $=220000$ MPa

$$ Beam length: $10$ m

$$ Simply supported type, supported at $0$ m and $8$ m

$$ Roller support at $0$ m and hinged support at $8$ m

$$ Cross$-$section of the beam: Rectangular, L$=350$ mm$,$ W $=250$ mm

$$ Point load of $50$ kN $(50000$ N$)$ applied at x $=10$ m

$$ Distributed load of $10$ kN$/$m $(10000$ N$/$m$)$ from x $=0$ to x $=8$

Show the screenshot of the beam with the various supports and the loads on

it as per the specifications given above.

Show the screenshots of the load on the beam.

Q$3$ Consider the concrete beam created using the simulation software Ftool in

Q$1.$

a$)$ Make the bending moment diagram and show its screenshot $(1$

marks$)$

As you move the cursor along the beam, the value of $$X$$ at the bottom of

the software changes. Get the values of $$X$$ at different points mentioned

below:$-$

b$)$ Give the value of maximum bending moment $($positive$)$ and its

location from left. Show the value of maximum bending moment

through calculation and compare these values $(3$ marks $+6$ marks$)$
