im not really given any values for EI-EII which is the configuration of the Au3-SCH3 molecule. instead, the length of the wire from the distance in which it was stretched. this is all in a graph dealing with nanwires.
The force required to elastically stretch a wire is given by:
F= ( l - lo / lo ) EA
where A is the cross-sectional area of the wire, lo is the length of the unstretched wire and l the length of the wire after it is stretched. E is the elastic modulus, sometimes called Young's modulus...
so these are considered the sign conventions of force? the positive/negative signs depending on the direction of the force of the object and other conditions?
hey there! i am taking a physical chemistry course at my college. an assignment given was about miniature machines: "pulling" nanowires. one of the questions asked is concerning the types of sign conventions of force. i have tried to research this topic had have trouble finding out the...
