While the two parallel ends shown in the figure are connected to each other with a metal rod, the other two ends are free. A conductive rod can slide freely on the rails.The speed of the stick is constant.In the figure, there is a magnetic field perpendicular to the plane and in the direction of which the size is 35 tesla.a) Since the distance between the rails is 25cm and the speed of the conductor rod is 55cm / sec, find the emk formed in the abcd frame consisting of the rail and the conductor rod.b) The resistance of the conductive rod is 18 ohms. If the resistance of the rails is neglected, find the current passing through the rod.c) What should be the magnitude of the external force that must be applied to the rod so that it can maintain its movement at a constant speed?d) Calculate the work done by the external force per unit time.e) Show that this work is equal to the heat energy spent on the rod resistance.

Fig. Q1(b) shows a rotational mechanical system with two masses with moment of inertia, J1 and J2. The T(t) is the applied torque to J1, while the θ1(t) and θ2(t) are the angular displacement of J1 and J2, respectively. Draw the free-body diagrams of mass with moment of inertia J1 and mass with moment of inertia J2, and then develop differential equations (with constant J1, J2, D1, D2, and K in the equations) that represent the mechanical system. Then using the given value of the constants in Figure Q1(b), derive the transfer function G(s) = θ2(s)/T(s) and the block diagram of the system.
An inclined plane of angle θhas a spring of force constant k fastened securely at the bottom so that the spring is parallel to the surface as shown. A block of mass m is placed on the plane at a distance d from the spring. From this position, the block is projected downward toward the spring with speed v. Calculate By what distance is the spring compressed when the block momentarily comes to rest? develop an equation for x. x when θ=30.0° , k = 1 kN/m, m = 5 kg, d = 0.5 m, and v =1 m/s. If we add another spring in series, by what distance is the spring compressed when the block momentarily comes to rest? If we add another spring in parallel, by what distance is the spring compressed when the block momentarily comes to rest?
When the 0.05 kg T-shaped body, which has a height of 80 mm and is 120 mm wide, is in the position shown, the torsional spring at O is pre-tensioned to exert a 0.75 Nm clockwise couple on the body. Determine the force P required to break contact at C. The body is in a vertical plane, so the weight does have an influence.
