Answer:
Here, The CML is used for efficient portfolios whereas the SML applies to all portfolios or securities
Considering the seperation theorem, The separation theorem states that the investment decision is sepaarte from the financing decision.
This implies that The SML can be used to analyze the relationship between risk and requried return for all assets.
Under the separation theorem investors should Hold the same portfolio of risky assets and the same expected return but at different levels of risk

Answer:
The escalator disposes 58 passengers each hour.
Explanation:
The velocity diagram of the escalator is shown in the attached figure
We can obtain the vertical distance that the escalator moves in 1 hour as
Thus in 1 hour the last thread moves 1720.73 cm
Now it is given that 1 thread = 600 mm =60 cm
Thus the number of times the last thread moves equals
Since each time last thread moves it disposes 2 passengers thus the number of passengers disposed when the thread moves 28.68 times equals
Thus the escalator disposes 58 passengers each hour.
Answer:
1. 142.1 GPa
2. 98.52%
Explanation:
1. The modulus of elasticity of carbon-epoxy composite is calculated using the following formula:
Ec = VmEm + VfEf
where Vm: volume of Epoxy
Em: modulus of the elasticity of the epoxy
Vf: volume of carbon fiber
Ef: modulus of the elasticity of the carbon fiber
Given that :
Vm = 0.6
Em = 3.5 GPa
Vf = 0.4
Ef: 350 Gpa
Therefore Ec = (0.6 × 3.5 GPa + (0.4 × 350 GPa)
Ec = 142.1 GPa
The modulus of elasticity of carbon-epoxy composite is 142.1 GPa
2. Percentage of load carried by the carbon fibers is given by the following equation: Ff/Fc = (Ef/Ec)×Vf
where Ff is the force carried by carbon fibers, Fc is the force applied to the composite, Ec is the modulus of elasticity of the composite, Ef is the modulus of the elasticity of the carbon fiber and Vf the volume of carbon fiber.
Given that:
EF = 350 Gpa
Ec = 142.1 GPa
Vf = 0.4
Substituting the above values into the equation:
Ff/Fc = (350 GPa/142.1 GPa)×0.4 = 0.9852 = 98.52%
The percentage of load carried by the carbon fibers is there 98.52%

Lathe is the manufacturing tools machines parts by moving the part into the cutting tool.
<u>Explanation:</u>
- The metals, other materials or wood are shaped as pieces using the machine tool which is lathe.
- Lathe is identified as three kinds: Engine lathe, Special purpose lathe, Turret lathe.
- Semi-portable and bench mounted are smaller ones.
- Floor mounted are large lathe it needs special transportations to move.
- Engine lathe can be moved from one area to another because its not too large. The lathe which is adapted many operations are used in maitanance shop.
- Special purpose lathe and Turret lathe is used in mass production.
