WebSep 12, 2024 · The ratio F/l is the force per unit length between two parallel currents \(I_1\) and \(I_2\) separated by a distance r.The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the … WebFormula for estimate the hoop stress of a cylinder is, Hoop stress = Internal diameter x Internal pressure/2 x Thickness. Mathematically hoop stress can be written as, σ θ = P.D/2t. Where, σ θ = Hoop stress in the direction of the both and unit is MPa, psi. P = Internal pressure of the pipe and unit is MPa, psi.

WebThe force per unit length can then be calculated using the known currents in the wires: F l = (4π × 10−7T ⋅ m/A)(5 × 10−3A)2 (2π)(5 × 10−2m) = 1 × 10−10N/m. The force from the first wire pulls the second wire. The angle between the radius and the x -axis is θ = tan−1(3 cm 4 cm) = 36.9°. The unit vector for this is calculated by WebApr 10, 2024 · Surface tension is a force per unit length acting in the plane of interface between the liquid and the bounding surface. Its unit is ‘N/m’ and the dimensions are [MT -2 ]. Due to surface tension, the liquid tries to reduce its surface. Law of Floatation: When an object is placed on liquid, an upthrust acts on it. chimney hill addition guthrie ok

WebIf current 0.2 A flows in both the wires in the same direction, calculate the force acting per unit length between them. Medium. View solution > If the distance as well as the current … WebMar 18, 2024 · (a) The force between the two wires is attractive. (b) The force per unit length between the two wires is (μ₀I²)/(2πd) Force between two parallel current-carrying wires: (a) It is given that two wires carry current in the same direction, so the force between the wires will be attractive. (b) The magnetic force between the two wires carrying … WebThe dimension of stress is the same as that of pressure, and therefore the SI unit for stress is the pascal (Pa), which is equivalent to one newton per square meter (N/m²). In Imperial units, stress can be measured in pound-force per square inch, which is abbreviated as psi. Using the Pressure, Stress, Young’s Modulus Converter Converter chimneyhillliving
