Chapter 5, Problem 8P

In the followign figure, axis y-y is fixed while axes x-x and z-z move with the arm. Gear 7 is fixed to the carrier. Gears 3 and 4, 5 and 6, and 8 and 9 are fixed together, respectively. Gears 3 and 4 move with planetary motion. If the tooth numbers are N,= 16T, N, = 20T, N.= 22T, Ns = 14T, N.= 15T, N; = 36T, Na= 20T, N,= 41T, and Nu= 97T, If the input speed is 1200 rpm, determine the speed and direction of the output shaft. 22T 20T 36T @z= 1200 rpm Output 15T y. Input Input - Output 14T 16T 20T 41T I97T 10 7.

Question 1: A race car is turning (cornering) on a flat road, as shown in Figure Q1-1. The speed of the car is 300 kph and the turning radius is 260 m. Having the car parameters as below, answer questions a) and b). ● . ● ● m = 890 (kg) (57% of the weight is on the rear axle); Air density = 1.225 (kg/m3); Equivalent aerodynamic lift coefficient for front axle= -0.915 (-); Aerodynamic frontal area= 1.11 (m²); Slip angle of the front tyres= +2.4 (°); Slip angle of rear tyres= +1.2 (°); The steering angle of wheels= -1.9 (°); The efficiency of the drivetrain from the engine to the contact patch of tyres is 100%. 8=-1.9°- ---R=260 m α = +2.4° αR = +1.2° Figure Q1-1 Motion of the vehicle and the angles a) Calculate the engine power delivered to tyres to overcome the total induced drag due to lateral force.

10-23 Problem 10-23 Clamping fixture. A holding fixture for a workpiece 37.5 mm thick at the clamp locations is being designed. The detail of one of the clamps is shown in the figure. A spring is required to drive the clamp upward when removing the workpiece with a starting force of 45 N. The clamp screw has an M10 X 1.25 thread. Allow a diametral clearance of 1.25 mm between it and the uncompressed spring. It is further specified that the free length of the spring should be Lo ≤ 48 mm, the solid height L, 31.5 mm, and the safety factor when closed solid should be n, 1.2. Starting with d = 2 mm, design a suitable helical coil compression spring for this fixture. For A227 HD steel, wire diameters are available in 0.2-mm increments between 0.2 to 3.2 mm.
