Answer:
0.65 m/min
Explanation:
The volume of material to be removed is
80*8*10 = 650 cm^3
The tool has a diameter of 4 mm and a maximum axial cutting capacity of 50 mm, so its cross section normal to advance is
0.4*5 = 2 cm^2
If the groove have to be made in T = 5 minutes the advance speed would be
V/(S * T)
650/(2 * 5) = 65 cm/min = 0.65 m/min
Answer:
Halo effect
Explanation:
In psychology, halo effect is defined as the tendency to assume that people with one positive attribute (e.g. physical attractiveness) also have other positive traits. Mere Exposure is the tendency to feel more positively toward a stimulus as a result of repeated exposure to it.
Answer:
<em>a) 42 mm</em>
<em>b) 144.4 MPa</em>
<em></em>
Explanation:
Load P = 200 kN = 200 x 10^3 N
Torque T = 1.5 kN-m = 1.5 x 10^3 N-m
maximum shear stress τ = 100 Mpa = 100 x 10^6 Pa
diameter of shaft d = ?
From T = τ * 
* 
substituting values, we have
1.5 x 10^3 = 100 x 10^6 x 
x
= 7.638 x 10^-5
d = ![\sqrt[3]{7.638 * 10^-5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B7.638%20%2A%2010%5E-5%7D)
= 0.042 m = <em>42 mm</em>
b) Normal stress = P/A
where A is the area
A = 
= 
= 1.385 x 10^-3
Normal stress = (200 x 10^3)/(1.385 x 10^-3) = 144.4 x 10^6 Pa = <em>144.4 MPa</em>
