Typically, when people say "net force" they are talking about bulk motion (it makes the whole object move). It doesn't have anything to do with structural integrity. Nor does a net force of zero mean there is no force acting on the object -- obviously, the two forces are still there.Scheuerf said:If an object is resting on a table and is pushed downward it has an opposite and equal normal force that counteracts the applied and gravitational forces making the net force on the object 0. If the net force on an object being pushed against a table is 0, how can it be crushed?
No net force means that the center of mass will not accelerate. Each end can certainly accelerate inward In a crushing motion, that is not restricted by the second law.Scheuerf said:If the net force on an object being pushed against a table is 0, how can it be crushed?
Crushing of objects due to forces is the process of applying external forces to an object that exceeds its structural capacity, causing it to break or deform.
Objects can crush under force due to factors such as their material properties, design, and the magnitude and direction of the applied force.
The material of an object plays a significant role in its crushing resistance. Objects made of stronger and more durable materials, such as steel, are less likely to crush under force compared to objects made of weaker materials like plastic.
Yes, objects can resist crushing under extreme forces if they are designed and constructed to withstand such forces. This requires a thorough understanding of the object's material properties and the magnitude and direction of the forces it will be subjected to.
Crushing of objects can be prevented through proper design and construction, using appropriate materials, and ensuring that the object is not subjected to excessive or unexpected forces. Regular maintenance and inspections can also help identify potential weaknesses and prevent crushing accidents.
