Answer:
It is sometimes called the factor label approach because units are treated as a factor (along with a numeric factor) in a quantity like 25 g, allowing us to subject the unit to algebraic operations as if they were variables.
Explanation:
It is sometimes called the factor label approach because we can treat a quantity like 25g as a product of a numerical factor and a unit factor, allowing us to subject the unit to arithmetic operations as if they were variables. Dimensional analysis can be most helpful when helping to set up a problem involving multiplication or division, but it is not limited to multiplication and division: Adding or subtracting quantities, for example, requires they have the same unit, just like adding algebraic terms 5x and 6x, and this rule can be used to help set up or check a calculation.
Answer:
500 N
Explanation:
Given;
Mass of the car, M = 1000 kg
initial speed of the car, u = 0 m/s
Final speed of the car, v = 60 m/s
Time, t = 1 min = 60 s
Now,
Force, F is given as:
F = Ma
where,
a is the acceleration
From the Newton's equation of motion, we have
v = u + at
on substituting the values, we get
60 = 0 + a × 60
or
a = 1 m/s²
Thus,
Force = 1000 × 1 = 1000 N
now,
this force will be equal to the friction force provided by the rear wheels
let the friction force on a single rear wheel be 'f'
thus,
2f = 1000 N
or
f = 500 N
Answer:
The definition is defined in the clarification segment following the table, as per the particular circumstance.
Explanation:
- In something like a closed-loop device, shaft encoders were being used, the output of which could be influenced either by encoder location. Most motors have been used for gearbox speed reduction (RPM). Assume there's also a gearbox reduction of 30:1 as well as the motor is already spinning at a higher 3000 rpm, then the outcome feature shaft speed would be 100 rpm.
- This suggests that every other output shaft turning correlates to 30 input shaft flips, and even if the encoder contains 40 holes through its diameter, instead every output shaft revolution contributes to pulses. That implies an accuracy of 0.3 degrees of rotation of the final output shaft .
Accuracy as well as reliability are thus given by positioning the encoder on the engine side instead of on the outcome shaft including its gear head.
Answer:
The temperature gauge showing that the vehicle has been running warmer or has recently began to have issues from overheating is an idication that your vehicle may be developing a cooling system problem.
