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 = = 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>
Answer:no fire can be used on fire
