Cranes are used to move loads from one location to another in minimum time such that the load reaches its destination without swinging. As we all know, that swinging problem occurs due to flexibility of wires but if the wire is rigid and permanently fixed on one side then the swinging problem will not occur.
As per the sketch there will be a telescopic arm and one side of the arm will be attached with the trolley of the crane. This rigid telescopic arm will be connected with the load at the time of lifting the load. In this way there will be no problem of swinging as the rigid telescopic arm will be fixed with the trolley and ...
NASA inventors have developed a set of puncture self-healing materials comprised of commercially available, known self-healing polymer resin and additive blends. A range of puncture healing blends was developed by melt blending self-healing polymers with non-self-healing polymeric materials.
Puncture healing capability of the melt blends improves at higher temperatures
Thermoplastic materials that can repeatedly and intrinsically self-heal without the need for foreign inserts or fillers (such as microencapsulated monomer)
Blend of self-healing polymer materials with high strength polymer resins potentially enables the materials to be used in structural, load bearing applications
Fuel tank liners
Healing layers in ballistic protection for armor, helmets and other personal protective equipment
