Solve A steel rail is 15m long and is laid at temperature of 25c. The maximum temperature expected is 45c
1. Estimate the minimum gag between two rails to be left so that temperature stresses do not develop.
2. Calculate the thermal stress develop in the rail if no expansion joint is provided.
3. Calculate the thermal stress developed in the rail if a 2.5mm gap is provided.

0.05Kg of steam at 15bar is contained in a rigid vessel of volume 0.0076m^3. what is the temperature of the steam

We would like to design a synchronous sequential circuit with two inputs A1 and A0, and one output Z. The two inputs are interpreted as a two-bit unsigned integer A1A0. Assume the input combination A1A0 = 11 will never happen. In other words, the inputs represent an integer from 0 to 2. The circuit will produce an output of 1 if the sum of the last two inputs in the input sequence is 2. Draw the state diagram of a Moore-type FSM for the circuit. Draw your diagram as clearly as possible.

Design a device to test one's reaction. The device has two inputs, G and R. G is controlled by the operator of the device, and R is controlled by a person under test. The device also has a single output, Z, equal to 0 when the device is not in use. The operator will push and then release G, which will turn a green light ON and OFF. Once the person under test observes the green light ON, he is supposed to push and release R before the green light is turned OFF. The output Z becomes 1 until G is released. If he fails to push and release R before the green light turns OFF, Z will not change.
(a) Draw state transition diagram of a Moore-type machine that describes the behavior of the device. (b) For this input sequence, find out the state and output of the machine in part (a) after each clock edge:
At 1st clock edge, GR = 00; 2nd, GR = 10; 3rd, GR = 11; 4th, GR = 01; 5th, GR = 00; 6th, GR = 10; 7th, GR = 10; 8th, GR = 11; 9th, GR = 10 ;10th, GR = 11; 11th, GR = 10; 12th, GR = 00
