Hace 4 días · As force per unit cross-sectional area. Select all of the following that would increase the stiffness of a cylindrical block of wood. Decrease its length. Increase its cross-sectional area. What magnitude of force is needed to produce the same amount of stretch (ΔL = ΔL0) in a string made of the same material, but having twice the cross ...
Hace 1 día · If velocity (V), force (F), and energy (E) are taken as fundamental units, then find the dimensional formula for mass. . Ans: Hint The given question is based on the conversion of the units to their dimensional formulae. Using the units of the force...
Hace 5 días · Hint : When two quantities are being added together or subtracted from each other the unit, thus dimension must be the same. The dimension of the right hand side must be equal to the dimension on the left and side of an equation. Complete step by step answer To get the dimensionally incorrect formula, we investigate them one after the other based on these two principles;
Hace 5 días · Introduction. When a body is free to rotate around an axis, torque must be applied to change its angular momentum.The amount of torque needed to cause any given angular acceleration (the rate of change in angular velocity) is proportional to the moment of inertia of the body.Moments of inertia may be expressed in units of kilogram metre squared (kg·m 2) in SI units and pound-foot-second ...
20 de jun. de 2024 · Newton’s second law is one of the most important in all of physics. For a body whose mass m is constant, it can be written in the form F = ma, where F (force) and a ( acceleration) are both vector quantities. If a body has a net force acting on it, it is accelerated in accordance with the equation. Conversely, if a body is not accelerated ...
26 de jun. de 2024 · The acceleration can also be explained as the rate of change of velocity with the time. Complete step by step answer: When a body is falling freely downwards, there will be an acceleration due to gravity towards the earth. The value of acceleration due to gravity is generally equal to $9.8m/s^2$. This can be denoted by the letter ‘g’.
