  1. ME-309 Static Force Analysis

  2. Example: The mechanism shown is drawn to scale 1cm : 0.2mUse graphical method to determine the torque needed for static equilibrium 3 Carry out all your graphical solutions on the scaled drawing of the given mechanism 2 We can consider the FBD of Links-3 4

  3. Example:Use graphical method to determine the torque for static equilibrium Add P1 & P2 C.P. Force Polygon h

  4. Consider a force scale as 1cm : 200N, then construct a parallelogram with this scale, and then measure R. R=4.4 cm 2.5 cm 4 cm R=4.4cm x 200N=880 N Back

  5. Consider a force scale as 1cm : 300N, then construct the force polygon for the three forces acting on link-3 and having the concurrency point (C.P.), then measure . C.P. 2.93 cm 2.4 cm F43=2.4 cm x 300N=720 N Back
