Given 5 nodes connected to a tdma network. furthermore, assume that the time-slot size is equal 20ms and that the nodes are perfectly time synchronized. the data rate of communication over this network is 500khz. what is the maximum number of bits that one node can transmit in one time slot (=maximum message size)? if all nodes are assigned a sequential timeslot (1, 2, 3, 4, 5, 1, 2, 3, 4, 5, 1, 2, what is the maximum latency of a message for node 1? assume that the message is maximum size. what is one of the main disadvantages of a tdma scheme?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Fluids at rest possess no flow energy. a)- true b)- false

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
