Answer:
a. Use datum on shaft
b. Use datum on hex flat
c. Use datum on face below the head
d. Use datum on shaft
When these datum are used, they will prevent translation and rotation along axis which they act.
Answer:
A

i just answered it on my test
Answer:
surface temp of fuel rod = 678.85 K
Explanation:
Given data :
D1 = 25 mm
D2 = 50 mm
T2 = 335 k
T∞ = 300 k
hconv = 0.15 w/m^2.k
ε2 = 0.05
ε1 = 1
Determine energy at Q23
Q23 = Qconv + Qrad
attached below is the detailed solution
Insert given values into equation 1 attached below to obtain the surface temperature of the fuel rod ( T1 )
Answer:
The pressure in tank will become 541.3 KPa.
Explanation:
From general gas equation we know that:
PV = nRT
PV = (m/M)RT
P/Tm = R/VM
Now, for initial state:
P1/T1 m1 = R/VM ______ eqn (1)
For Final State, as the gas constant (R), volume (V) and molecular mass of air (M) remains constant;
P2/T2 m2 = R/VM ______ eqn (2)
Comparing eqn (1) and eqn (2):
P1/T1 m1 = P2/T2 m2
Now, we have:
P1 = 400 KPa
P2 = ?
m1 = 2 kg
m2 = 0.6 kg + 2 kg = 2.6 kg
T1 = 20°C = 293 K
T2 = 32°C = 305 K
Therefore,
(400 KPa)/(293 K)(2 kg) = P2/(305 K)(2.6 kg)
<u>P2 = 541.3 KPa</u>
That part of the material which is not affected by either stress is the neutral line or axis.
<h3>What is the technique known as whilst you bend steel?</h3>
Sheet Metal Bending – Methods, Design Tips & K Factor. Bending is one of the maximum not unusual place sheet steel fabrication operations. Also referred to as press braking, flanging, die bending, folding and edging, this technique is used to deform a cloth to an angular shape. This is finished thru the utility of pressure on a workpiece.
The neutral axis is in which neither the fabric stretches nor is compressed. Hence, the duration of the nuetral axis lives the identical earlier than and after the bending operation.
