How do you calculate shear stress in a shaft? Shear Stress in Shafts Shear Stress in a Solid Shaft Equation. When torque or twisitn loading is applied to a cylindrical shaft, a shearing stress is applied to the shaft. The shear stress in a solid cylindrical shaft at a given location: σ = T r […]
Do convergent boundaries cause volcanoes?
Do convergent boundaries cause volcanoes? If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. Where […]
Why is velocity zero at pitot tube?
Why is velocity zero at pitot tube? At the open end of the pitot tube the velocity of the fluid becomes zero. But that should result in accumulation of liquid inside the pipe which is not possible. Why is stagnation point important? The stagnation point represents the location of the start of the leading edge […]
What are the 2 biological effects of ionizing radiation?
What are the 2 biological effects of ionizing radiation? The biological effects of ionizing radiation are due to two effects it has on cells: interference with cell reproduction, and destruction of cell function. Which radiation is responsible for oncogenic transformation? Class I PI3K consists of four isoforms, PI3K α, β, γ, and δ, each with […]
Which is not characteristic of pure substance?
Which is not characteristic of pure substance? the characteristics which does not represent a pure substance is that they are made up of different types of particles. Explanation: pure substances include elements and compounds. They have same boiling and melting point. What are the types of pure substance? The two main types of pure substances […]
What are two ways to increase the resistance in a wire?
What are two ways to increase the resistance in a wire? length – longer wires have greater resistance. thickness – smaller diameter wires have greater resistance. temperature – heating a wire increases its resistance. What are three ways to decrease resistance in a wire? Changing the material, increasing the cross section area, lowering the temperature, […]
What is the best solvent for recrystallization?
What is the best solvent for recrystallization? For a solvent pair, the first solvent should readily dissolve the solid. The second solvent must have a lower solubility for the solute and be miscible with the first solvent. Common solvent pairs include ethyl acetate and hexane, toluene and hexane, methanol and dichloromethane, and water and ethanol. […]
What causes the pail to move in circular motion?
What causes the pail to move in circular motion? As a bucket of water is tied to a string and spun in a circle, the tension force acting upon the bucket provides the centripetal force required for circular motion. As the moon orbits the Earth, the force of gravity acting upon the moon provides the […]
What happens to the current in a circuit if a 1.5 volt battery?
What happens to the current in a circuit if a 1.5 volt battery? What happens to the current in a circuit if a 1.5- volt battery is removed and replaced by a 9-volt battery? The current would increase. 10. The relationship between resistance and current in a circuit is that the greater the resistance the […]
