The mechanism, as shown in Fig., has the dimensions of various links as follows: AB = DE = 150 mm; BC = CD = 450 mm; EF = 375 mm. The crank AB makes an angle of 45° with the horizontal and rotates about A in the clockwise direction at a uniform speed of 120 r.p.m. 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, and 3. rubbing speed at the pin C which is 50 mm in diameter.

A steel plate 100 mm wide and 10 mm thick is joined with another steel plate by means of single transverse and double parallel fillet weld as shown in figure below. The strength of the plates to be joined is equal to strength of welded joint. The permissible tensile and shear stress for weld and plate material are 70 MPa and 50 MPa, respectively. Find the length of each parallel fillet weld.
