Answer 1

Answer:

Step-by-st60 mm long line AB is parallel to and 20 mm in front of the VP The ends A and B of the line are 10 mm and 50 mm above the H.P, respectively. Draw the projections of the line and determine its inclination with the H.Pep:

Answer 2

Answer:

The projections of the line and determine its inclination with the H.P

θ = 36.87°

Step-by-step explanation:

From the above question,

They have given :

Given: Line AB : 60 mm long, parallel to and 20 mm in front of the VP

In engineering drawing, the term 'projection' refers to the representation of a three-dimensional object in two-dimensional space. Projections are used to represent the object from different angles and to illustrate the relationship between the various parts of the object. In order to draw the projections of a three-dimensional object, the object must first be placed in the orthographic plane.

A: 10 mm above HP

B: 50 mm above HP

The projections of the line AB will be as shown in the figure below:

The inclination of the line AB with the H.P. will be equal to the angle θ formed by the line AB and the H.P.

Orthographic projection is the most common type of projection used in engineering drawings, as it is the most accurate and precise type of projection. Oblique projection is similar to orthographic projection, but it is less precise and less accurate. Axonometric projection is the least accurate type of projection, but it is useful for providing an overall view of an object.

θ = $tan^-1$ ( (50 - 10) / 60 )

θ = $tan^-1$ ( 40 / 60 )

θ = $tan^-1$ ( 0.6667 )

θ = 36.87°
