Webmakes an angle of 45° with the horizontal and rotates about A in the cw direction at a uniform speed of 120 rpm. The lever DC oscillates about the fixed point D, which is connected to AB by the coupler BC. The block F moves in the horizontal guides, being driven by the link EF. Determine: 1. Velocity of the block F 2. Angular velocity of DC 3. WebAs shown in Figure Q1(a), a single horizontal force P = 900 N is applied at end D of lever ABD which is fix-supported at end A. Knowing that portion AB of the lever has diameter of 36 mm, determine the state of stresses at point H and sketch the stress element.
