Question 1. The homogeneous gate shown in Figure consists of one quarter of a circular cylinder and is used to maintain a water depth of 6+a/10 m. That is, when the water depth exceeds 6 + a/10 m, the gate opens slightly and lets the water flow under it. Determine the weight of the gate per meter of length. (y-9,81 KN/m³). Pivot 6+ b/10 m 2+ a/10m 4R 3x = = 0.05488R I =-0.01647R Hint: le) Quarter-circle

In the mid-20th century, the availability and the growth in power of digital computers led to the increase in the mathematical model in the field of engineering and science. The analysis of these detailed models needs to be increased.
