Answer:
moment of inertia = 4.662 * 10^6 
Explanation:
Given data :
Mass of machine = 400 kg = 400 * 9.81 = 3924 N
length of span = 3.2 m
E = 200 * 10^9 N/m^2
frequency = 9.3 Hz
Wm ( angular frequency ) = 2
= 58.434 rad/secs
also Wm =
------- EQUATION 1
g = 9.81
deflection of simply supported beam
t = 
insert the value of t into equation 1
W
=
make I the subject of the equation
I ( Moment of inertia about the neutral axis ) = 
I =
= 4.662 * 10^6 
As a free and open operating system, Android allows app developers to generate new ideas and work with a wide range of smartphones to open up hardware options, as companies supply a great variety of devices to choose from and high-end devices become more affordable.25 Jan 2017
Answer:
The final pressure is 3.16 torr
Solution:
As per the question:
The reduced pressure after drop in it, P' = 3 torr = 
At the end of pumping, temperature of air, 
After the rise in the air temperature, 
Now, we know the ideal gas eqn:
PV = mRT
So

(1)
where
P = Pressure
V = Volume

R = Rydberg's constant
T = Temperature
Using eqn (1):



Now, at constant volume the final pressure, P' is given by:



Answer:
Option A, B and D
Explanation:
Jack can easily convince boss if he focus around two major aspects of the company
a) Revenue enhancement - Jack must outline the benefits of his research that can be used to improvise customer offerings and hence can be further used to devise more energy-efficient options to customer
b) Reduction in mistakes - Issues such as poor implementation can be avoided with better approach and understanding.
Hence, option A, B and D are correct
Answer: Technician A
Explanation: A coolant recovery system Is one of the most important part of a vehicles cooling system. When a coolant gets too hot, it forces it way out of the spring loaded radiator cap so as to relieve pressure. Any coolant which has escaped is recovered back through the discharge tube located in the recovery tank. The system is usually air free
