Define concrete hollow block?
While concrete has been used as a building material for many centuries, concrete hollow blocks have only been manufactured since the early 1900s. These blocks are used in all types of building projects.
What is the advantage of gravity die casting over high pressure die casting?
The tooling for gravity casting costs less than pressure die casting but the part cost in pressure die casting is much less. see Sand Casting. Die Casting: In the high pressure, requires a die casting machine to inject molten liquid or semi-liquid metal to a higher rate of die-casting mold cavity filling and solidification under pressure, forming and casting methods obtained. Gravity Casting: Uses the gravity or weight of the metal to fill the cavity producing a metal part. It does not require the use of an expensive die casting machine. The tooling cost is lesser for gravity casting because of the lower pressures needed to produce parts.
Which is the strongest component die casting or forging or sand casting?
Forging
Which casting making petrol engine carburetor?
Pressure Die Casting
What is the difference between die casting and pressure die casting?
In sand mold casting the molten metal is poured in to the mold cavity , while in pressure die casting the molten metal is forced under high pressure in to the cavity. The sand casting process is used for small batch production where pressure die casting is used for mass production.
Where are charges located on a hollow sphere?
If the sphere is conducting, all the charge is distributed uniformly on the outer surface of the sphere.
The electrical intensity inside a charged hollow sphere is?
Zero, because the electric field inside a charged hollow sphere is zero. This is due to the Gauss's law and symmetry of the charged hollow sphere, which results in no net electric field inside the sphere.
What is potential inside the hollow charged sphere?
Inside a hollow charged sphere, the electric potential is constant and zero throughout the interior of the sphere. This is because the electric field due to the charges on the outer surface cancels out within the hollow region, resulting in no work done on a test charge to move it within the hollow sphere.
What is the formula for calculating the moment of inertia of a hollow sphere?
The formula for calculating the moment of inertia of a hollow sphere is I (2/3) m r2, where I is the moment of inertia, m is the mass of the sphere, and r is the radius of the sphere.
Is hollow an adjective?
Yes, it can be (a hollow sphere, a hollow sound). The word hollow can also be a noun, meaning a gap, void, or a small valley.
What is the shape of a tenis ball?
a 44mm sphere that is hollow
How many sides does sphere have?
A sphere has one side. Not tricky! Unless the sphere is hollow, which would have two sides, inside and outside.
How many curved surface does a sphere have?
One if it is solid, two if it is hollow
How do you charge metallic hollow sphere?
touch it with a charged object....
What is a solid figure with no edges and two faces?
A hollow sphere.
Is a hollow metal sphere electrically neutral?
Yes, a hollow metal sphere is electrically neutral because the charges inside cancel each other out, resulting in a net charge of zero.
Will a solid metal sphere hold a larger electric charge then a hollow sphere of the same diameter and where does the charge reside in each case?
No, a hollow sphere can hold a larger electric charge compared to a solid sphere of the same diameter because the charge resides on the outer surface in both cases. In a hollow sphere, the charge distributes uniformly on the outer surface, allowing it to hold more charge without experiencing as much repulsion between like charges as a solid sphere.
