Option choice b is the correct answer
Answer:
W = 11,416.6879 N
L ≈ 64.417 cm
Explanation:
The maximum shear stress, 
, is given by the following formula;
= 1 cm = 0.01
h = 29 cm = 0.29 m
= 25 cm = 0.25 m
b = 15 cm = 0.15 m
= The centroidal moment of inertia
= 1/12*(0.15*0.29^3 - 0.15*0.25^3 + 0.01*0.25^3) = 1.2257083 × 10⁻⁴ m⁴
Substituting the known values gives;
= 1.2257083
× 10⁻⁴ m⁴
From which we have;
Which gives;
W = 11,416.6879 N
= 1500 N/cm² = 15,000,000 N/m²
= 15,000,000 × 1.2257083 × 10⁻⁴ ≈ 1838.56245 N·m²
From Which we have;
L ≈ 0.64417 m ≈ 64.417 cm.
Answer:
0.25 J/K
Explanation:
Given data in given question
heat (Q) = 100 J
temperature (T) = 400 K
to find out
the change in entropy of the given system
Solution
we use the entropy change equation here i.e
ΔS = ΔQ / T ...................a
Now we put the value of heat (Q) and Temperature (T) in equation a
ΔS is the entropy change, Q is heat and T is the temperature,
so that
ΔS = 100/400 J/K
ΔS = 0.25 J/K
