Answer:
procedure attached below
The material to be used will have a %Cw of 34.5%Cw which is < 40%Cw
Explanation:
<em>Given data:</em>
Minimum tensile strength = 865 MPa
Ductility = 10%EL
Desired Final diameter = 6.0 mm
20% cold worked 7.94 mm diameter 1040 steel stock
<u> Describe the procedure you would follow to obtain this material.</u>
assuming 1040 steel experiences cracking at 40%CW
<em>attached below is a detailed procedure of obtaining the material</em>
The material to be used will have a %Cw of 34.5%Cw which is < 40%Cw
Answer:
1.1⁰C
Explanation:
Width W = 5mm = 0.005
Thickness t = 1 mm = 0.001
K = thermal conductivity = 150W/m.K
P = q = heat transfer rate = 4W
We are to find the steady state temperature between the back and the front surface
We have to make these assumptions:
1. There is steady state conduction
2. The heat flow is of one dimension
3. The thermal conductivity is constant
4. The heat dissipation is uniform
We have:
∆t = t*P/k*W²
= (0.001m x 4W)/150x(0.005)²
= 0.004/0.00375
= 1.06667
This is approximately,
1.1⁰C

Explanation:
<u>Lean manufacturing</u>
Lean manufacturing, a philosophy developed by Toyota Production System are means to eliminate wastes. They are defined as the techniques or management activities in eliminating wastes and increasing the efficiency inside an organisation.
According to the concept of lean manufacturing, mainly seven types of wastes are identified. They are :
1. Transportation waste
2. Inventory waste
3. Over production
4. Waiting
5. Defects
6. Motion waste
7. Non utilized talent
All these waste affect greatly to the efficiency of an organisation and devalue its services. Lean manufacturing advises to prevent all these waste in order to increase the productivity.
All the management activities and techniques used in lean manufacturing may be different according to the business application but they are all based on the same basic principle of removing wastes and errors and increase efficiency.
The different sectors that are benefiting from lean manufacturing methodology are
Healthcare
Hospitality
Food and Beverage
Government
Manufacturing
Lean manufacturing can be used in different sectors.
