Answer:
force = 5.969 kN
Explanation:
given data
diameter of the hole D = 10 mm
thickness of sheet metal T = 1 mm
ultimate tensile strength = 190 MPa
solution
force is express as
force = ultimate tensile strength × Area ............1
and here area will be
area = π × D × T ................2
area = π × 10 × 1
area = 31.4159 mm²
so put value in equation 1 we get
force = 190 × 31.4159
force = 5969.02 N
force = 5.969 kN
Answer:
C. Low viscosity for Maine in the winter and high viscosity for Florida in the summer.
Explanation:
The choice of motor oil or engine oil depends on the type of engine and also on the type of climate on which the engine runs.
In winter climates, we should use oil with low viscosity as at lower temperatures, the it flows more readily if its viscosity is low.
But the summer season needs a relatively thicker oil so as to reduce the thinning effect of the oil out of the engine.
Thus for Maine in the winter season, we need a low viscosity oil and for Florida a high viscosity oil in the summer season.
Therefore, option (c) is correct.

Explanation:
Automation is a technology by which processes that are normally meant to be controlled by humans are electronically controlled. These can be through the use of robots, computer aided machines, etc.
For small scale industries, expensive automation should not be employed, it should rather be low cost, because of the financial abilities of these firms.
Low cost automation will improve the production of small scale industries in limited time. Humans cannot match up with machines that have been incorporated with programmable comptrollers in carrying out production processes. Such machines operate at a higher speed and Efficiency.
For example, In a small packaging company, microrobots can be made to serve this purpose while saving the continual cost of labour and at the same time ensuring efficiency.
A small mechanic workshop that decides to employ an automatic diagnostic tool will be more efficient and productive than the one that uses manual approach.
Should be c.
