Answer: If saturation effects are ignored, the magnetization curve of Fig. 7.27 becomes a straight line with a constant slope of 150 volts per ampere of field current.
Explanation:
The intensity w of the distributed load so that the average normal stress in the rod AB does not exceed 390 kPa are the 3 N/m.
<h3>What is a strain?</h3>
Strain is the quantity of deformation skilled via way of means of the frame withinside the path of pressure applied, divided via way of means of the preliminary dimensions of the frame. The following equation offers the relation for deformation in phrases of the duration of a solid: ϵ = δ l L.
- Assume that the common regular strain withinside the rod AB is the standards of failure.
- Calculate the withinside the rod AB the usage of the subsequent formula: sigma AB = T A A AB sigma AB Here, is the common regular strain withinside the rod AB, A AB is the cross-sectional region rod AB
- 390 kPa*( 10^ 3N/m^ 2 1 kPa ) fOr sigma AB and Substitute
- 10 mm^ 2 *( 10^ -6 m^ 2 1 mm^ 2 ) for A AB:i equation. the above
- 390/10 ^ 3| = T_/(10|10 ^ - 6|) T_ = 3N.
- Determine the importance of w through thinking about the moments approximately factor C . sum M c =zero
- T_ * (L) + [(1/2)(6)(w)](L/three) = zero (2)
- Substitute three N for T_ and six m for L withinside the equation (three).
- - 3(6) + [(1/2)(6)(w)](6/3) = zero w = 3N / m

Explanation:
A ductile material can convert into brittle material due to following reasons
1.At very low temperature
2.Due to presence of notch
In titanic ,the base of ship strike to the large ice cube and lower part of titanic ship material was made of steel .We know that steel is ductile material and when steel came with very low temperature of ice due to this ductile material converted in to brittle material and titanic ship failed.Brittle material does not show any indication before failure.
