A scooter has hydraulic disc brakes both front and rear. The brakes have a brake piston on each side of the disc. The average radius of the blocks' contact with the disc is 10 cm, the piston diameter is 20 mm and the steel disc weighs 0.8 kg. The coefficient of friction between the coating and the disc is assumed to be 0.4. The scooter weighs 160 kg including the driver and the weight distribution is 50% front and 50% rear regardless of whether you brake or not. The wheelbase (the distance between the center of the front and rear wheels) is 1.37 m and the wheel diameter is 0.45 m. Assume that you only brake with the front wheel and that the friction number between the tire and the road surface is 0.9. Steel has a specific heat capacity of 450 J / (kg ° C).
- What is the minimum possible braking distance (you brake so hard that the front wheel is on the verge of locking) when braking from 50 km / h to a standstill?

Sphere A has a charge of +10.0 C.It is brought in contact with a neutral sphere B and then separated.Find the final charges on spheres A and B if the spheres have equal radius and if the radius of sphere B is twice the radius of sphere A
in a three-wheel planetary gear, the sun gear has 19 teeth and the planet wheels 17 teeth each. The teeth are not profiled. The energy is fed in via the sun wheel and taken out via the planetary bar. The load must be driven with a power of 1,000 W and rotated at a speed of 1,200 rpm. The efficiency between sun gear and planet gear is assumed to be 0.98 and between planet gear and ring gear to 0.96
- How many teeth does the outer sun gear have?
- What gear ratio does the gear have?
- What is the efficiency of the gear unit??
- What speed should the engine rotate with?
- What torque must the engine deliver?
