Nitroglycerin tablets and sprays prescribed as heart medication contain tiny amounts of nitroglycerin diluted by inert matter and are completely nonexplosive. http://antoine.frostburg.edu/chem/senese/101/redox/faq/nitroglycerin.shtml
I will strike the nail with the hammer. I strike the nail with the hammer. I struck the nail with the hammer. I have struck the nail with the hammer.
In passive voice, the sentence "The hammer might have struck him" is transformed by making the object of the active sentence (him) the subject of the passive sentence, using the appropriate form of the verb "to be" (in this case, "been") and the past participle of the main verb (struck). The modified sentence in passive voice is: "He might have been struck by the hammer." In this passive construction, the emphasis is on the receiver of the action (him), rather than the doer of the action (the hammer). The subject of the passive sentence (him) is now affected by the action of being struck by the hammer.
The hammer might have hit him to change into his passive voice.
Percussion; specifically, an anvil, that he struck with a hammer.
A reflex hammer is the triangular rubber-headed mallet with which your knee is struck during a physical exam.
Yes, that means it's malleable, like Gold.
A coin will get warmer when struck by a hammer just like a nail will. The energy of the hammer blow is converted into heat. The atoms and molecules in the coin will be compressed a great deal by the hammer blow, and this will break metallic crystal bonds in the metal matrix. This creates heat. The energy of the hammer blow must be conserved, and heat is a large part of the equation.
A hammer will shatter some things that are chemically bonded, and will not shatter others. Glass, ice and even diamonds can be "broken" with a hammer. They are solids and have the quality of being brittle to a lesser or greater degree. But other materials will definitely not shatter when struck by a hammer. If you struck a tire with a hammer, you'd be hitting it all day without shattering it. (But if you cryogenically cool the rubber and hammer it, it will shatter with ease.) Whether or not a material that is chemically bonded will shatter when struck by a hammer depends on the material. We need to note, however, that the hammer will not generally break the chemical bonds themselves when the material shatters. The hammer just breaks the macroscopic (perhaps crystalline) structure of the material.
An electric bell is basically a metal dome that vibrates when struck by a small hammer. An electromagnet is used to make the hammer strike the bell, moving the hammer back and forth very quickly.
A percussion cap is struck by a spring loaded hammer causing detonation of the exposive.
When the surface is struck the initial hit is just the rubber face and the plastic or metal housing of the mallet, the significant force if from the weight inside moving from the back of the hammer to the striking face after it is struck. So the significant blow comes when the hammer is not moving or dead. This helps keep the surface that is being struck from being damaged.
