1) angle of rest:
2) The angle between the horizontal and the plane of contact between two bodies when the upper body is just about to slide over the lower. Also known as angle of friction.
About 32 degrees according to Britainica Encyclopedia.

It is the natural maximum stable surface slope angle of a particulate medium.
This is the maximum angle than an inclined plane may be tipped before an object begins to slide. The coefficient of static friction can be determined by multiplying this angle by tangent.
The angle of repose is the angle between the horizontal surface and the sloping surface of the pile.

Solid gypsum density is 2312 to 2322 kg/cubic meter or 2.312 to 2.322 g/cc. These are "as measured" values indicating some variation in the gypsum crystals. By the molecular formula, calcium sulfate with two water molecules should weigh 2.308 gm/cc. If not solid, then broken gypsum density ranges from 1290 to 1600 kg/m3.
This boardis similar in composition to Type X drywall, except that it has more glass fibers, and, it has another ingredient in the gypsum core. This ingredient is a shrinkage-compensating additive, a form of vermiculite. When exposed to high heat, the gypsum core shrinks but the shrinkage-compensating element expands at about the same rate as shrinkage occurs in the waterdepleted gypsum. The gypsum core then is more stable in a fire and remains in place even after the combined water in the gypsum has been driven off.
it is sometimes white, and also sometimes some look like regular rocks
No, gypsum cannot scratch topaz. Minerals with a higher number on the Moh's Hardness Scale can scratch minerals that are lower-numbered, but lower numbers can't scratch higher numbers. A mineral would have to have a number higher than an 8 on the Moh's hardness scale in order to scratch topaz.
Right angle (90) Acute angle (<90) Obtuse angle (>90) Straight angle (180) Reflex angle (>180)
22o is the angle of repose.
22o is the angle of repose.
yes, angle of friction is equal to angle of repose.
Angle of repose is equal to angle of friction.
The angle of repose for salt is about 32 degrees.
Q. What is angle of repose for lime stone?
It is the Emptying Angle of Repose that is greater than the Filling Angle of Repose. It is always the greater of the two Angles of Repose.
The angle of repose for dry shelled corn is 23 degrees or a tangent of .42
"Angle of Repose" is a novel by Wallace Stegner published in 1971. The novel won the Pulitzer Prize for Fiction in 1972.
it is as like as viscous liquid so the angle of repose for it under 30 deg
Angel of repose is different from the angel of friction; however in a particular case it may be the same. Basically angle of repose is an engineering property of granular materials. It is the maximum angle of a stable slope determined by friction, cohesion and the shapes of the particles. When bulk granular materials are poured onto a horizontal surface, a conical pile will form. The internal angle between the surface of the pile and the horizontal surface is known as the angle of repose and is related to the density, surface area and shapes of the particles, and the coefficient of friction of the material. Material with a low angle of repose forms flatter piles than material with a high angle of repose. In other words, the angle of repose is the angle a pile forms with the ground. While angel of friction is the angle between the noemal force and athe resultant between tha normal force and friction force.
In Wallace Stegner's novel, "Angle of Repose," the term "angle of repose" refers to the steepest angle at which loose material remains stable without sliding down. Metaphorically, it can represent the point at which one's life or relationships reach a precarious balance, ready to either hold steady or fall apart.
