Principle of transmissibility

 

Principle of transmissibility:

If a force is acting at a point on a body then it is assumed that the point of application of a force can be transmitted anywhere on its line of action within the body (without disturbing its condition of equilibrium). 

Following figure shows the force F is acting at a point 'A' on the body and the new position is represented at point 'B' on the same line of action, within the body.

  (Q.2)   The acceleration of the particle is defined by the relation a = 25 - 3x 2 mm/s 2 . The particle starts with no initial velocity at the position x = 0. (a) Determine the velocity when x = 2 mm (b) the position when velocity is again zero, (c) position where the velocity is maximum and the corresponding maximum velocity. (Q.3)   Acceleration of a particle moving along a straight line is represented by the relation a = 30 - 4.5x 2 m/s 2 . The particle starts with zero initial velocity at x = 0. Determine (a) The velocity when x = 3 m, (b) the position when the velocity is again zero (c) the position when the velocity is maximum. Solution:  (Q.6)   A stone is dropped from the top of a tower. When it has fallen a distance of 10m, another stone is dropped from a point 38 m below the top of the tower. If both the stones reach the ground at the same time calculate (i) the height of the tower (ii) the velocity of the stones when ...

  (Q.1) A force 5 kN is acting along AB where A (0, 0, -1) m and B (5, -2, -4) m. Another force 8 kN is acting along BC where C (3, 3, 4) m. Find resultant of two forces and find moment of  resultant force about a point D (0, 3, -2). (Q.2) A force acts at the origin in a direction defined by the angles θ v = 65 o and θ z = 40 o Knowing that the x - component of the force is 750N, determine (i) the other components (ii) magnitude of the force (iii) the value of θ x . Solution:  (Q.3) Find the resultant of the spatial concurrent force system concurrent at A(1,0,0) and passing through points B (-1,3,5), C (3,5,7), D (0,4,0). Magnitudes of forces are, F AB = 100 N, F AC = 150 N, F AD = 200 N.   (Q.4) Force 5 KN is acting along AB where A(0, 0, -1) m & B(5, -2, -4) m. Another force 8 KN is              acting along BC where C...
