No.1 (a) In the figure on the right, crank r = 250 mm, connecting rod 1 = 1500 mm. What is the displacement x of the piston when 0 = 30 °? At this time, if the rotation speed of the crank is constant at 1200 rpm, find the piston speed. Terwt 4 Piston. Crank mechanism N m (b) In the free vibration system shown on the right, the spring constant k = 1800 and the mass m = 0.15 kg. Find the natural angular frequency, natural frequency, and period of this vibration. m ܐܢ ww -wf (c) In the figure on the right • Piston mass mp=0.3kg • Mass of connecting rod m +1.5kg . Connecting rod length 1+30cm (center of gravity G is in the center) • Crank radius of gyration r 8cm • Rotation speed 2000 rpm There is a mechanism. At this time, find the inertial forces X and Y, respectively. (The notation of sin wt and cos wt can be left as it is) Piston. Crank mechanism
