The integrations needed to determine beam deflections require the enforcement of the appropriate displacement and rotation boundary conditions (BCs). It is important that we be able to recognize these ...

HELSINKI — China will aim to alter the orbit of a potentially threatening asteroid with a kinetic impactor test as part of plans for a planetary defense system. China is drafting a planetary defense ...

When used in structural engineering, the term deflection refers to load-induced displacement, which typically affects beam designs. It can be an extremely complicated value to calculate when ...

In civil engineering, flexural beams are used to control the effect of vibrations that can cause cracks to appear in surfaces (concrete slabs) and beams. This is particularly important in buildings ...

The mission managers at NASA spent $330 million to send a refrigerator-sized spacecraft 7 million miles (11 million km) into space and punch an asteroid in the nose. And we should all be very glad ...

Planetary scientists have published a detailed follow-up on the debris from their historic 2022 asteroid impact experiment in outer space. What they found challenges their understanding of the ...

NASA has a launch date for that most Hollywood of missions, the Double Asteroid Redirection Test, which is basically a dry run of the movie “Armageddon.” Unlike the film, this will not involve nukes, ...
