A wire of diameter 1 mm breaks under a tension 0f 1000 N. Another wire, of same material as that of the first one, but of diameter 2mm breaks under a tension of
The breaking tension of a wire is proportional to its cross-sectional area. It can be determined using the formula: A = (π × d²) / 4 Step 1: Determine the areas First wire (diameter = 1 mm): A₁ = (π × 1²) / 4 = π / 4 Second wire (diameter = 2 mm): A₂ = (π × 2²) / 4 = 4π / 4 = π The area of the seconRead more
The breaking tension of a wire is proportional to its cross-sectional area. It can be determined using the formula:
A = (π × d²) / 4
Step 1: Determine the areas
First wire (diameter = 1 mm):
A₁ = (π × 1²) / 4 = π / 4
Second wire (diameter = 2 mm):
A₂ = (π × 2²) / 4 = 4π / 4 = π
The area of the second wire is **4 times** the area of the first wire.
Step 2: Calculate the breaking tension
Breaking tension is proportional to the area.
For the first wire:
T₁ = 1000 N
For the second wire:
T₂ = 4 × T₁ = 4 × 1000 = 4000 N

What is the recommended posture for practicing sectional breathing? Name the suggested sitting postures.
For sectional breathing, postures like Vajrāsana, Vīrāsana, Padmāsana, and Sukhāsana are recommended. These sitting positions ensure the spine remains erect, the body stays relaxed, and the breathing process is unhindered. Maintaining a straight spine aligns energy flow, while relaxed facial and bodRead more
For sectional breathing, postures like Vajrāsana, Vīrāsana, Padmāsana, and Sukhāsana are recommended. These sitting positions ensure the spine remains erect, the body stays relaxed, and the breathing process is unhindered. Maintaining a straight spine aligns energy flow, while relaxed facial and body muscles support mindfulness. Practicing in these postures enhances Prānāyāma’s effectiveness, enabling deeper, rhythmic breathing and fostering physical and mental balance.

The ratio of longitudinal stress to longitudinal strain is called Young's Modulus or the Modulus of Elasticity. It is a measure of the stiffness of a material and is expressed mathematically as: \[ E = \frac{\text{Longitudinal Stress}}{\text{Longitudinal Strain}} \] Where: - \(E\) is Young's ModulusRead more
The ratio of longitudinal stress to longitudinal strain is called Young’s Modulus or the Modulus of Elasticity. It is a measure of the stiffness of a material and is expressed mathematically as:
\[
E = \frac{\text{Longitudinal Stress}}{\text{Longitudinal Strain}}
\]
Where:
– \(E\) is Young’s Modulus (typically measured in pascals, Pa).
– Longitudinal stress is the force applied per unit area (\(\sigma = \frac{F}{A}\)).
– Longitudinal strain is the deformation per unit length (\(\varepsilon = \frac{\Delta L}{L}\)).
Young’s Modulus is a fundamental property of materials, determining how they deform under tensile or compressive loads.
