1. Determine the general formulas of the speeds of the programs and the number of speeds of the programs. 2. Construct a sequence using the final speed of each program. Is there any relation between these speeds? 3. Determine the number of speeds of program 10, and the value of speed number 7 within program 10.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
Task 2
The cells of the battery are treated using a programmable lathe machine. The machine has 15
programs that are able to control its speed.
can vary from 100 revolution per minute (rev/min) to 1100 (rev/min). Program 2 has 13 ( N
(2) =13) speeds that can vary from 110 rev/min to 1430 rev/min ( X1(1) = 100, X2(1)=110,
and so on). The number of speeds of the higher programs increases using geometric progression
and the speeds within the same program follow the same pattern of the common difference
achieved in program 1 and 2 and increase using arithmetic progression.
1. Determine the general formulas of the speeds of the programs and the number of
speeds of the programs.
2. Construct a sequence using the final speed of each program. Is there any relation
between these speeds?
3. Determine the number of speeds of program 10, and the value of speed number 7
within program 10.
4. Determine the total number of speeds that can be produced.
5. Determine the value of the maximum speed that can be produced by the lathe
machine.
6. If a speed of 3000 rev./min is required to handle a specific manufacturing task, which
(program/s) can be used to achieve it exactly. On the other hand, if the program
cannot achieve the speed of 3000 rev./min; recommend the speed that can be used
and the program that can provide the closest value of 3000 rev./min.
7. Repeat a-f if the number of speeds is increased arithmetically (N is now arithmetic)
and the speeds within each program is varied geometrically ( Xi, i=1: 15)using the
same pattern
