41⟩ Explain what do you mean by Break Lines?
It is used to limit a broken section. For short break an uneven freehand thick line is recommended and for long breaks a long thin ruled dashes joined by freehand ‘ Zig Zags’ are used.

No, It will not work,as the Compression ratio of Petrol engine is 6 to 10 & that of Diesel engine is 15 to 22. Thus on such high compression, gasoline gets highly compressed & it may blast.
It is a process to estimate various aspects of software product in order to calculate the cost of development in terms of efforts, time and resources. This estimation can be derived from past experience, by consulting experts or by using pre-defined formulas.
It is a device to do drawing work neatly and quickly.An attachment provided to move any position and may be adjusted at any required height.
Maintenance in the manufacturing environment is one of the most complicated types of maintenance in comparison to construction, transportation and service business. Manufacturing is becoming highly competitive with extremely high pressure in reducing cost and increasing value of assets and improving the quality of outcomes (products). Manufacturing systems has grown over the years to be parts of global networks and supply chains. All of these changes in the manufacturing business have put maintenance in a great pressure on developing more effective and efficient operations.
Other special feature of manufacturing environment that makes it distinct from other environment is its complicated interrelation with large number of stakeholders, internal and external. The management structure in manufacturing environment is usually highly structured with many several decision layers and many parallel functional areas.
These are thick lines used to indicate the location of cutting planes in sectioning and the viewing position of removed pieces.
It is the ratio of drawing to the object. R.F=Length of the object in the drawing /Actual length of the object.
There are seven major elements of TPM as follows:
☛ housekeeping on the production line,
☛ cross-training of operators to perform maintenance tasks,
☛ teams of production and maintenance personnel,
☛ operator involvement in the maintenance delivery system,
☛ disciplined planning of maintenance tasks,
☛ information tracking of equipment and process condition and plans,
☛ Schedule compliance to the maintenance plan.
1) The buckets along with sand should be placed inside the workshop.
2) Switches and other electrical parts must be made of fireproof material.
3) Carbon dioxide gas should be place at required points in special containers.
4) Fire extinguishers of suitable type should be placed at accessible places.
A drawing which is worked out an engineer for the engineering purpose is known as Engineering Drawing.
Chain dimensioning can be used where the possible accumulation of tolerance does not cause danger to the functional requirement of the part.

sizes are available.
First Aid is immediate and temporary care given to a person who affected accidental injury or a sudden illness before the arrival of doctor.
☛ Maintenance philosophy
☛ Maintenance load forecasting
☛ Maintenance capacity
☛ Maintenance scheduling.
Centreline is a thin line in the form long and short dashes. It indicates area of symmetrical parts, circles and path of motion.
Maintenance forecasting is a major part of planning concerned with estimating the current and future amount of maintenance work and type needed. Maintenance load forecasting is a complex task that involves a lot of uncertainties and influenced by many factors such as the age of the equipment, the rate of use, usage climate, and skills of workers.
An accident is a unexpected and unforeseen event which may or may not injury to a person or a machine tool.
These are thin lines composed of long dashes with pair of short dashes. Phantom Lines used to show adjacent parts, alternate positionsand the lines of motion.
Divide the shaft diameter size by 5, it will give last two digit of the bearing no. and according to type of load we have to chose the type of bearing and that will give prior no. of the bearing.
Capacity planning is the translation of the maintenance load into resource needed to meet the forecasted load. Resources include, number and skills of craftsmen, maintenance tools, labor, material, spare parts, etc.
