Answer:
a) the two-way concrete joist framing system
Explanation:
A waffle slab is also known as ribbed slab, it is a slab which as waffle like appearance with holes beneath. It is adopted in construction projects that has long length, length more than 12m. The waffle slab is rigid, therefore it is used in building that needs minimal vibration.
Answer:
No
Explanation:
Carnot heat engine:
Carnot heat engine is an ideal heat engine for all working heat engine.It have all processes are reversible and have four processes in which twom are constant temperature process and other two constant entropy processes.
As we know that efficiency of Carnot cycle given as follows
Where
So from above expression we can say that efficiency of heat engine does not depends on the working fluids.

Answer:
Explanation:
Modulus of resilience is the maximum amount of strain that an elastic material can support per unit volume, without deformation, and is calculated using the following equation:
<em>μ = σ^2 ÷ 2*E</em>
<em>σ = yield strain</em>= force / cross area
force = 500N; area=π*=
σ =
<em>E= young modulus</em>: <em>relation between stress and strain, measures stiffness</em>
E=σ/∈, where
∈=(L-Lo)/Lo=7*
where
<em>L=current length</em> = 10 cm * 1.007 = 1.0070* m
<em>Lo=original lenght</em> = 10 cm = 1.0*m
so, E=σ/∈ =
<em>μ = modulus of resilience = </em>
