Answer / jose h jones

it is based on strain energy principle

Answer / pooja

Castigliano's theorem is exactly based on strain energy
principle ,which gives the deflection & load acted ata
point .
From castigliano's 1st theorem ...., we can get the
deflection at a point of the body, by getting derivative of
strain energy wrt. the load acted at that point.
From castigliano's 2nd theorem ...., we can get the load at
a point by getting the derivative of total strain energy
wrt. the deflection at that point.

Answer / henry chijoke

1st theorem: the strain energy of a conservative system is
expressed in terms of N-independent displacement degree of
freedom, then the load that corresponds to degree of
freedom. 2nd theorem: partial derivative of the
complimentary strain energy wrt load yields the
displacement component of the loaded point in the direction
of that load.....

Answer / akhilesh

if we are taking 2 points in a member a and b.
then if we apply load on point a then there some diflection
will occure at point b. than again if apply load on b than
there some deflection at a. the diflection at both the
point will same.

Why we test compressive strength after 28 days..?

3 Answers   NM Caramoan Builders,

1) a)to prepare mortar for bricklaying how much amount of water should be added for its maximum strength and workability(to avoid cracks which results, when high quantity of water is added)?is their a formula or ratio? b) suppose we want to make 1:3 mortar,what is the best way to measure cement ,sand and water and how? c)time before which freshly prepared mortar should be used? d)proper way to mix and make mortar? e)when should curing start after laying bricks and for how long?and also how many hours per day? f)what is shear wall (please in terms of layman lol) bookish definisions are confusing.... g) and last,acc to codes what are max no. of course that should be laid in a day.
