Twist produced in a cylinder
Given data:
- Length of the cylinder (L) = 1.5 m
- Diameter of the cylinder (D) = 4 cm
- Tangential force applied (F) = 4 × 10^5 N
- Rigidity modulus of the cylinder (G) = 6 × 10^10 N/m^2
Calculation:
Step 1: Finding the radius of the cylinder
The diameter of the cylinder is given as 4 cm. To find the radius, we divide the diameter by 2.
Radius (r) = D/2 = 4 cm / 2 = 2 cm = 0.02 m
Step 2: Calculating the torque applied
The torque (τ) applied to the cylinder can be calculated using the formula:
τ = F × r
Substituting the given values:
τ = (4 × 10^5 N) × (0.02 m)
τ = 8 × 10^3 Nm
Step 3: Calculating the twist angle
The twist angle (θ) can be calculated using the formula:
θ = τ / (G × L)
Substituting the given values:
θ = (8 × 10^3 Nm) / (6 × 10^10 N/m^2 × 1.5 m)
θ = 8 × 10^3 Nm / 9 × 10^10 Nm
θ = 8 / 9 × 10^-7 rad
Result:
The twist produced in the cylinder is approximately 8 / 9 × 10^-7 rad.
