1. Problem 15: Fv & Tv of a triangular plate are shown.
Determine it’s true shape.
USE SAME PROCEDURE STEPS 50
OF PREVIOUS PROBLEM: 25
BUT THERE IS ONE DIFFICULTY: c’
15
NO LINE IS // TO XY IN ANY VIEW. a’
1’
MEANS NO TL IS AVAILABLE.
20
IN SUCH CASES DRAW ONE LINE b’
// TO XY IN ANY VIEW & IT’S OTHER 10
X Y
VIEW CAN BE CONSIDERED AS TL 15
x1
FOR THE PURPOSE. a c
HERE a’ 1’ line in Fv is drawn // to xy. 40
HENCE it’s Tv a-1 becomes TL. 1 c’1
a’1 y2
b
THEN FOLLOW SAME STEPS AND
c1
DETERMINE TRUE SHAPE. b’1
(STUDY THE ILLUSTRATION) y1
x2
ALWAYS FOR NEW FV TAKE b1
DISTANCES OF PREVIOUS FV
AND FOR NEW TV, DISTANCES d1
OF PREVIOUS TV
REMEMBER!!
