Hello!

(text reading time 2 min)

I can solve this problem, but result seems to be a little large.

Please help me check it.

PRELIMINARY

Set Mode RPN , flag 117, Checked for SOFT MENU.

Acess Equation Library

So access

[EQLIB], in the softmenu

after

[EQNLI], in the softmenu

So will appear a Equation Library menu, so go to:

COLUMNS AND BEAMS

and press ENTER

now choose

CANTILEVER DEFLECTION

Problem 01

Calculate the cantilever deflection

at the edge of a beam of steel, of square section,

as shown in the picture, with lenght of 20m.

Data:

L =20m (length)

E = 200 000 000 kPa

(Elasticity Module or Young's Module, for steel E = 200GPa)

I = b.h3/12 = 200 x 300³ /12 = 450 000 000 mm4 (moment of inertia)

a = 10m (distance from wall to the point of load)

P = 20kN (load point)

c = 12m (distance to app. moment

M = 5kN.m (app moment)

w = 8kN/m (distributed load)

x = 20m (at the edge, x=lenght)

y =? (variable to calculate)

To me t is y = -195 cm.

Is it right?
