Answer:
If this is what I think it is...
Explanation:
Rate: 1 sheet per 4 paragraphs, 1 page for every four students
Unit Rate: 500 sheets per ream, 40 pages for each booklet, 15 pages for each booklet
Neither: 25 pages
Step-by-step explanation:
To do this you just need to remember the difference between Unit Rate and Rate, the Unit rate make reference to those rates in which the numerator is one, so you saying there are 3 candies for each kid, that is a unit rate, saying there is one kid for every three candies that is a rate, so that´s how you divide them, that´s why even though 1 sheet per 4 paragraphs, 1 page for every four students have one in their fractions, they are rates and not unit rates because the one is not in the numerator.
Let's not take into account atmospheric pressure.
Pressure P = Pressure of oil column + Pressure of water column
= h1 . d1.g + h2.d2. g
=( 0.5 x 800 x 9.8) + ( 1x 1000x 9.8) = 3920+ 9800 = 13720
Hence guage pressure at bottom is
P= 13720 N/ m^2
The answer is most likely Biological because insects and other organisms thrive in stagnant water.
Answer:
Tmax = 2.934ksi
φ = 4.58°
Explanation:
Given.
Length = 100 ft
Maximum power = 2590 hp
Angular rotate = 1700 rpm .
Outer diameter of the shaft = 8 in. Wall thickness = 3/8 in.
Calculating angular velocity.
= 1700rev/min * 2πrad/rev * 1min/60s
= 56.67πrad/s
Convert power to ft.lb/s
2590hp = 2590 * 550
= 1424500ft.lb/s
At this point, we calculate torque.
Torque = Power/Angular Velocity
Torque = 1424500/56.67π
Torque = 8000.24lb.ft
Using the torsion formula, we'll calculate maximum stress due to the shear force acting on the body:
Tmax = ½(Tc/J)
Tmax =½ of (8001.24 * 12 * 4 )/ (π/4)(4⁴ - 3.625⁴)
Tmax = ½ * 5868.656298363693
Tmax = 2934.328149181846
Tmax = 2.934ksi
Calculating the angle twist
φ = TL/JG
φ = (8001.24 * 12 * 100 * 12 )/( (π/4)(4⁴ - 3.625⁴)(4⁴ - 3.625⁴)(11)(10^6))
φ = 0.08002 rad -- convert to degrees
φ = 4.58° --- approximated
