Answer:
Plain Bearings and Rolling Element Bearings -
Explanation:
two different type of bearing are:
1) Plain Bearings - Plain bearings are the easiest form of bearings and consist of only the layer of the bearings without rolling components.
2)Rolling Element Bearings - Rolling element bearings use balls or rollers between two rings – allowing movement with little rotating and sliding friction. These type of bearings include bearings for balls and rollers.
Answer:
809.98°C
Explanation:
STEP ONE: The first step to take in order to solve this particular Question or problem is to find or determine the Biot value.
Biot value = (heat transfer coefficient × length) ÷ thermal conductivity.
Biot value = (220 × 0.1)÷ 110 = 0.2.
Biot value = 0.2.
STEP TWO: Determine the Fourier number. Since the Biot value is greater than 0.1. Tis can be done by making use of the formula below;
Fourier number = thermal diffusivity × time ÷ (length)^2.
Fourier number = (3 × 60 × 33.9 × 10^-6)/( 0.1)^2 = 0.6102.
STEP THREE: This is the last step for the question, here we will be calculating the temperature of the center plane of the brass plate after 3 minutes.
Thus, the temperature of the center plane of the brass plane after 3 minutes = (1.00705) (0.89199) (900- 15) + 15.
= > the temperature of the center plane of the brass plane after 3 minutes = 809.98°C.
Answer:
Correct option is A - O(x)
Explanation:
Given f(x) = 10 and g(x) = x
Hence f(x) is O g(x)
As such correct answer is O(x) which is option A
