Bond length or development length = d*tensilestress/4*bond stress.
D*1400/4*6 = 58.33.
D*1400/4*6 = 58.33.

The increase of length due to bending stress is called bond length.
Bond length = (diameter/4)X stress/strength.
= 1400x D/ 4x6.
= 59 D.
Bond length = (diameter/4)X stress/strength.
= 1400x D/ 4x6.
= 59 D.

Bond length = tensile stress * Diameter of rod/(4 times bond strength).
= 1400 * D/(4 * 6),
= 1400 * D/24,
= 59D.
= 1400 * D/(4 * 6),
= 1400 * D/24,
= 59D.

Ld = 0.87Fy/4 τ bd.
This will gives answer as 50.75.
So answer will be 50 times the diameter.
This will gives answer as 50.75.
So answer will be 50 times the diameter.

Tensile stress = 1400.
Bond stress = 6.
Bond length = 1400*D/4*6 = 58.33.
Hence, the answer is 59D.
Bond stress = 6.
Bond length = 1400*D/4*6 = 58.33.
Hence, the answer is 59D.

Acc. to wsm Ld = (1400*D)/(4*6) = 58.33.
Acc. To LSM Ld=(.87 *1400 *D)/(4*6) = 50.75.
Acc. To LSM Ld=(.87 *1400 *D)/(4*6) = 50.75.

(D*1400)÷(4*6)=58.33,
Say=59D.
Say=59D.

Ld = 1400/(4 * 6).
= 58.3 =>59.
= 58.3 =>59.
