A vertical gate 6 m x 6 m holds water on one side with the free surface at its top. The moment about the bottom edge of the gate of the water force will he (y is the specific weight of water

Consider the robotic arm shown below, made up of individual arms ?B and ?C. The weight ofthe arms AB and ?C are each 160 N, and the resultant weight force is shown to act through eacharm’s center of gravity as shown. You may assume that the center of gravity is occurring along themidpoint of each arm’s length. The robotic arm is picking up a package that weighs 40 N, and the40 N weight force acts through the package’s center of gravity at the location shown. a) A servomotor at point B is exerting a torque value to resist the rotation inducedby the weight force of the robotic arm BC and the weight force of the 40 N package.Calculate the required torque at point B necessary to resist the moment caused by therobotic arm BC and the 40 N package. Indicate the direction of the required torque (↺ or↻). Report your answer in N-m.b) A servomotor at point C is exerting a torque value to resist the rotation inducedby the weight force of the 40 N package. Calculate the required torque at point C…
