Q4. As shown in the image below, a force of P= 310 N is applied to the 64-kg cart. The dimensions are a = 0.29 m, b = 0.21 m, and c = 0.28 m, and the angle 0 = 26. The mass center of the cart is at point G. Assume the wheels are weightless and free to roll (therefore, friction can be ignored). Take g = 9.81 m/s?. (1) Determine the total normal force at the wheels at A. A FBD and kinetic diagram must be included on your notes. Your answer must include 1 place after the decimal point, and the proper SI unit. P 0.4 m C В 0.08 m
4. Draw the FBD and derive the EOM of the pulley system below with respect to x using Newton's laws. Mass m slides on a rough surface with friction force f. There is no displacement in the spring initially. -Pulley. moment of inertia J,
A single cylinder reciprocating engine has speeded 300 RPM. Stroke 250 mm, mass of reciprocating parts 50 kg. Mass of revolving parts at 150 mm radius 37 kg. If two fourth of the reciprocating parts and all the revolving parts are to be balanced, find (i) The balance mass required at 400 mm radius (ii) The residual unbalanced force when the crank has rotated 45° TDC.
