##L2Q2 The reaction forces on the front and rear tire markings of a horizontally parked passenger vehicle are respectively Fz1 = 4562.3N and Fz2 = 3168.0. Suppose the length of the vehicle is 2.65m. a) Determine the position of the center of mass of this vehicle b) Make a diagram showing the position of the center of mass in relation to the front and rear wheels.

The spool shown in the figure has a weight of WAB and its center of gravity is located at its center geometric 0, the spool has a larger radius R and an inner radius r and has a coiled string. Block C has a uniform weight WC. Consider the friction between block C and the top of the spool at A, between the spool and the surface at point B, and between the rope and pulley D, the friction coefficients are respectively: us @ A, us @ B and us @ D. The rope is parallel to the plane. Carry out: a) The free-body diagrams of the block and reel. b) The calculation of the maximum value of P that can be applied without losing the equilibrium of the system. c) Indicate the number of unknowns and what they are Radius (m) Weights (N) Friction coefficients WC us @ A us @ B us @ D R WAB 0,12 0,08 30,00 55,00 0,45 0,20 0,30

1–2. Figure C1.2 shows a mechanism that is typical in the tank of a water closet. Note that flapper C is hollow and filled with trapped air. Carefully examine the configuration of the components in the mechanism. Then answer the following leading questions to gain insight into the operation of the mechanism. 1. As the handle A is rotated counterclockwise, what is the motion of flapper C? 2. When flapper C is raised, what effect is seen? 3. When flapper C is lifted, it tends to remain in an upward position for a period of time. What causes this tendency to keep the flapper lifted? 4. When will this tendency (to keep flapper C lifted) cease Plz connect me if you want to explan subject for me .... +962 79180149 Thx
