A velomobile is a fully-faired tricycle. The combined mass of the velomobile and the rider are 103 kg. The drag coefficient of the area is C_d = 0.076 based on a frontal area of 0.41 m^2. The coefficient of friction for the tires is mu = 0.0055. For travel on a standard day, (a) draw a free body diagram of the velomobile (b) determine the maximum velocity of the velomobile for a sustained power input (F middot V) of 150W (c) speed limits arc either 25 mph or 35 mph on my route should I be concerned with getting a ticket?

Solution

The loaded four wheel trailer shown in Figure P8.10 has a total mass of 5t and is pulled along a level road. Average resistance to motion (friction and windage) is 2 per cent of the total weight and acts at the same horizontal level as the applied force P. Determine the normal reaction at each of the front and rear wheels when the trailer moves:

a) at constant velocity

b) with forward acceleration 1.5m/s².

(Average resistance to motion is 2% of total weight is not required.)
