Dynamic Force Analysis 1 6 Force Analysis Homework 11: Joint reaction forces and equilibrium moment Problem 6.3 The mechanism in Fig. P6.3 has the dimensions: AB =200 mm, AC =600 mm, BD =1000 mm, L a =150 mm, L b =250 mm, and EF =600 mm. The driver link 1 rotates with a constant angular speed of n =60 rpm. The links are homogeneous rectangular prisms made of steel with the width h = 0 . 01 m and the depth d = 0 . 001 m. The steel sliders 3 and 4 have the width w Slider = 0 . 05 m, the height h Slider = 0 . 02 m, and the depth d = 0 . 001 m. The density of the material is ρ Steel = 8000 kg/m 3 and the gravitational acceleration is g = 9 . 807 m/s 2 . The external moment on 5 is opposed to the motion of the link M ext = M 5 ext = -| M ext | ω 5 | ω 5 | , where | M ext | = 900 N · m. Find the equilibrium moment on link AB and the joint reaction forces for φ = φ 1 =120 . For φ =120 the kinematics of the mechanism are given by: x B =-0.1 m, y B =0.173205 m, x C =-0.6 m, y C =0 m,
