4.2.6 Robert’s Mechanism Fig. 4.13: The Robert’s Mechanism Robert‘s linkage is another four-bar approximate straight line generator mechanism with coupler point C. Good results can be obtained with construction parameters d = 1‚ b = 0.538 ‚ a = c = 0.530 e = f = 1.04. Robert‘s mechanism generates a curve which has a linear part parallel to the base link. Links and coupler curve are symmetric.[20] The limitation of this mechanism is that the straight line path is very short

Causes and mechanisms of water resources degradation Logging of forest Logging is the cutting‚ skidding‚ on-site processing‚ and loading of trees or logs onto trucks. Logging and the subsequent denudation of the forest cover increases surface runoff since there is less oppurtunity for rainwater to sink into the ground. .Retarded or supressed infiltration accelerates overland flow production‚hastening delivery of rainwater into streams and rivers‚ the oftentimes the water ends up as floodwater
