In plastic limit analysis of structural members subjected to bending, it is assumed that an abrupt transition from elastic to ideally plastic behaviour occurs at a certain value of moment, known as plastic moment (Mp). Member behaviour between Myp and Mp is considered to be elastic. When Mp is reached, a plastic hinge is formed in the member. In contrast to a frictionless hinge permitting free rotation, it is postulated that the plastic hinge allows large rotations to occur at constant plastic moment Mp.
Plastic hinges extend along short lengths of beams. Actual values of these lengths depend on cross-sections and load distributions. But detailed analyses have shown that it is sufficiently accurate to consider beams rigid-plastic, with plasticity confined to plastic hinges at points. While this assumption is sufficient for limit analysis, finite element formulations are available to account for the spread of plasticity along plastic hinge lengths.
By inserting a plastic hinge at a plastic limit load into a statically determinate beam, a kinematic mechanism permitting an unbounded displacement of the system can be formed. It is known as the collapse mechanism. For each degree of static indeterminacy of the beam, an additional plastic hinge must be added to form a collapse mechanism.

How do you collapse quinny pushchair?
To collapse a Quinny pushchair, first ensure that the seat is in the upright position. Locate the folding mechanism, usually found on the handle or the side of the frame, and press or pull it according to the model's instructions. While doing this, gently push the handlebar downwards to fold the pushchair. Once collapsed, secure it with any locking mechanism if available to prevent it from unfolding.

How are bees dying?
Colony Collapse Disorder is a mechanism which is causing the death of worker bees and the corresponding, sudden collapse of the bee colony/hive. The exact cause is still unknown, although there is a lot of research in this area. The only factor that seems common to all cases of CCD is "nutritional stress", where the colony has suffered from malnutrition prior to the event.
