The engine of an automobile generates a force that causes the wheels to turn. As the wheels turn, they exert a force on the road. More specifically, the wheels push back on the road. The road pushes forward on the wheels. This forward force is the force of static friction, and is responsible for pushing the automobile forward. Using the same logic, explain how a propeller-driven airplane moves forward.

T d 3D 5 ст m Fr Figure Q3 Figure Q3 above shows the schematic of a motor on the right pulling the mass on the left. It is known that a kinetic friction force exists between the block and the floor, with its magnitude F; = HzN, where u, = 0.3 and Nis the normal force on the block. The mass of the block m is 150 N. From an initial velocity of v; = 0 ms-1, it is required that the block reaches a velocity of v; = 2 ms-1 after 0.9 seconds.
The figure shown below (Fig. 1) is a schematic representation of a conversion system linear-rotational motion. The system consists of a piston with one degree of freedom of movement (vertical displacement) connected to a connecting rod-crank. The necessary vertical force to be applied on the piston in order to convert the vertical displacement into shaft rotation varies according to the piston position. The figure shows only one instant of the system in which the vertical force applied is equal to 35 KN. Considering this instant as static (that is, imagine that the axis is applying a moment of such magnitude that it counteracts the displacement of the piston) solve the following subsections. Fig. 2 shows the actual geometry of the connecting rod (element ab) of the schematic system. a) Calculate what should be the minimum thickness ? of the connecting rod (element ab) if to guarantee its structural safety the stress must not exceed a value of 160 MPa at any of its points. Consider the…

An automobile tire can be critically statically balanced since it has an dimension. A system of masses rotations in different plane is in dynamic balance if the resultant O A. Couple is equal to zero O B. Force and the couple are both equal to zero O. Force is numerically equal to the resultant couple O D. Force is equal to zero Car engine mechanism is the inversions of kinematic chain.
Kinematics is the branch of dynamics which deals with the motion of bodies without referring to the forces causing the motion of the body. Select one: True False
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

You and a friend are raising a beam, but your friend's rope is too short so you lift him off the ground. At the current time, everything is static. The tension in your cord is 1045.6 N, the mass of the beam is 15 kg, and the mass of your friend is 85 kg. The length of the beam is 4.9 m, d = 3.9 m, theta = 43.5 degrees, phi = 62.5 degrees. If you choose the base of the beam as the origin, and the positive torque direction as counter-clockwise, what is the torque from your cord on the friend+beam system?
