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
Answer:
Engineering
Explanation:
STEM mainly incorporate knowledge from four disciplines which are:
- Science
- Technology
- Engineering
- Mathematics
The field of engineering combines concepts mainly from Science and Mathematics then with the help of technological developments using software, engineering field designs various structures and other elements that are essential to humanity.

Answer:
The hardenability increases with increasing austenite grain size, because the grain boundary area is decreasing. This means that the sites for the nucleation of ferrite and pearlite are being reduced in number, with the result that these transformations are slowed down, and the hardenability is therefore increased.
