Explanation:
Answer: For tiny leaks in pipes, use a compound stick available at most hardware stores. Simply rub the stick over the hole to stop the leak. The compound stick can even stop small leaks while the water is still running in the pipe. Epoxy paste can be applied only to dry pipes, and the water must be turned off. repair clamps An epoxy putty can be applied over the source of the leak to temporarily seal it. Immediately turn off the water supply upstream of the leaking pipes. Drain the water from the damaged line and ensure that the area to be patched is clean and dry so that the epoxy will properly adhere to the pipe.

Answer:
Area under the strain-stress curve up to fracture gives the toughness of the material.
Explanation:
When a material is loaded by external forces stresses are developed in the material which produce strains in the material.
The amount of strain that a given stress produces depends upon the Modulus of Elasticity of the material.
Toughness of a material is defined as the energy absorbed by the material when it is loaded until fracture. Hence a more tough material absorbs more energy until fracture and thus is excellent choice in machine parts that are loaded by large loads such as springs of trains, suspension of cars.
The toughness of a material is quantitatively obtained by finding the area under it's stress-strain curve until fracture.

Answer:
0.577
Explanation:
Answer:
Explanation:
Parameters given:
Angle = 30°
Mass of block = 5kg
Velocity = 6 m/s
Time = 4s
Frictional force is given in terms of Normal force as:
F = uN
Where u = coefficient of frictional force
N = normal force
Frictional force is given as:
F = mgsinθ
Normal force is given as:
N = mgcosθ
Coefficient of friction is therefore given as:
mgsinθ = u * mgcosθ
=> u = sinθ / cosθ
u = tanθ
u = tan(30°)
u = 0.577
