A “proof round” is an ammunition assembly designed to be used in proof testing; this can use a fixed cartridge, a semi-fixed cartridge, or separately loaded projectile, charge and primer. A “proof shot” is a special projectile used in a proof round or other projectile weapons, electromagnetic guns for example.
Q. Which force is being applied by the boy is hitting a ball with a bat?
gravitational force
Q. What is proof load in spring?
Proof load is the maximum load carrying capacity of the spring, without getting permanently distorted.
Q. What is the proof load?
Proof load is defined as the maximum tensile force that can be applied to a bolt that will not result in plastic deformation. In other words, the material must remain in its elastic region when loaded up to its proof load. Proof load is typically between 85-95% of the yield strength.
Q. What is a proof load guns?
In a proof test, a proof load is handloaded to a maximum pressure that the firearm should be able to take without causing plastic deformation, which is usually about 25 percent more pressure than the maximum pressure of the cartridge the gun is chambered in. The gun is loaded with it and fired twice.
Q. What is the difference between working load limit and safe working load?
WLL and SWL are abbreviatons for Working Load Limit (WLL) and Safe Working Load (SWL). The main difference between the two terms is that SWL is the older term. Today, SWL isn’t used anymore because the term is completely replaced with WLL and MRC.
Q. What is load capacity?
Load capacity is the maximum allowable force that can be applied to a stage in a specified direction while meeting stage specifications. This maximum force includes static (mass × gravity) and dynamic forces (mass × acceleration).
Q. What will be the breaking force when a wire can withstand the maximum load?
Answer: Breaking force = Breaking stress × Area of cross-section. When the wire is cut to half, there is no change in the area of cross-section of the wire. Therefore, there is no change in the maximum load (i.e., breaking force) the wire can support.
Q. Can we determine the maximum load a wire can support justify your answer?
If the wire is cut to half its value, the maximum load it can sustain is. which is independent of length of wire.
Q. What force is required to stretch a steel wire?
The force required to stretch a steel wire of 1 cm^2 cross-section to 1.1 times its length would be [Y = 2 × 10^11 (N / m^2)]
Q. When the length of the wire is halved from its original length the maximum load that can be tolerated so that the wire does not break?
Answer Expert Verified The breaking force is directly proportional to the cross-sectional area of the wire and not its length. Similarly, breaking stress is dependent only on the material of the wire and not its size. Thus, when an elastic wire is cut into half, there is no effect on the maximum load it can support.
Q. What force would be required to stretch a wire of 3 * 10 4?
what force would we require to stretch a wire of 3*10 -4 cross section so that its length becomes 2.5 times its original length? fiven that y=3.6*1012 dyne/cm.
Q. What force is required to stretch a copper wire 1 cm square in cross section to double its length?
Hence, the required force is 107N.
Q. What force is required to stretch a wire?
2×107N.
