A rectangular gate 3 meters high and 1.2 meters wide is hinged at the top. A force to keep the gate closed is applied at the bottom with an angle of 45 degrees with the vertical. Compute the following if the water surface is 0.9 meters below the top of the gate. Use 9.81kN/m as water's specific weight. the total hydrostatic force acting on the gate in kN; the distance of the total hydrostatic force from the centroid of the gate in m; and the magnitude of the force at the bottom of the gate in kN. Note: Do not round off intermediate values. Answer in four decimal places and do not include units in your answers.

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
