The force in the spring will be .
The deflection of the beam will be =
A rigid, horizontally extending structural member known as a cantilever is supported at only one end. Typically, it extends from a solidly affixed flat vertical surface, such as a wall.
Given that:-
- A cantilever beam AB of length L has fixed support at A and spring support at B.
- The spring behaves in a linearly elastic manner with stiffness k. If a concentrated load P is applied at B.
The spring force will be calculated as:-
Deflection will be given by:-
The spring force will be calculated by:-
The deflection of the beam will be given as:-
Therefore the force in the spring will be ..The deflection of the beam will be
=

Answer:
The sum of all currents entering a junction is 0
Explanation:
Current cannot disappear, so the currents leaving a junction have to equal the currents entering a junction. If you would give the currents leaving the junction an opposite sign (e.g., negative) it implies that the sum of all these currents is exactly 0.
