Question

Problem Sheet No- 01 1. From A (15, -40, 20) draw a horizontal (forward right) line AB (50 mm long, $\beta = 20^\circ$) and a frontal (downward right) line AC (65 mm long, $\alpha = 30^\circ$). From D draw a profile line DE (D is on AC and E is on AB). Find $\alpha$, $\beta$ and true length of DE. Find the missing co-ordinates of D and E. D (25, ?, ?); E (?, ?, ?).

Step 1

We need to find the coordinates of points B and C first, then use the given information about D and E to find their coordinates, and finally calculate the true length and angles of DE. **1. Define the coordinate system and initial point A:** Let the coordinates Show more…
