Answer:
Your question is lacking some information attached is the missing part and the solution
A) AB = AD = BD = 0, BC = LC
AC =
B) AB = AD = BC = BD = 0
AC =
Explanation:
A) Forces in all members due to the load L in position A
assuming that BD goes slack from an inspection of Joint B
AB = 0 and BC = LC from Joint D, AD = 0 and CD = 4L/3 C
B) steps to arrive to the answer is attached below
AB = AD = BC = BD = 0
AC =
Answer:
a)
b)Mass in lb = 376.8 lb
Mass in slug = 11.71 slug
c)
d)
Explanation:
Given that
d= 2 ft
r= 1 ft
h= 3 ft
Density
a)
We know that volume V given as
b)
Mass = Density x volume
mass= 376.8 lb
We know that
1 lb = 0.031 slug
So 376.8 lb= 11.71 slug
Mass in lb = 376.8 lb
Mass in slug = 11.71 slug
c)
we know that specific volume(v) is the inverse of density.
d)
Specific weight(w) is the product of density and the gravity(g).
w= ρ X g
w = 40 x 31.9
Answer:
The correct answer is option 'c': 13.8 kNm
Explanation:
We know that moment of a force equals
The hydro static force is given by
We know that the hydrostatic pressure on a rectangular surface in vertical position is given by
For the given rectangular surface we have
Thus applying the values we get force as
This pressure will act at center of pressure of the rectangular plate whose co-ordinates is given by h/3 from base
Thus applying the calculated values we get
