A hydraulic lift is used to raise a 900 – kg car. If the diameters of the small and large pistons are 8 cm and 0.8 m, determine the force that is exerted on the small piston.

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…

The brake system in most cars makes use of a hydraulic system. This system consists of a fluid filled tube connected at each end to a piston. Assume that the piston attached to the brake pedal has a cross sectional area of 0.6 cm2 and the piston attached to the brake pad has a cross section area of 2.4 cm2. Determine the force at the brake pad, if you apply a force of 10 N to the piston attached to the brake pedal. Please show the formulae, the calculations, all the steps.

Your engineering firm is asked to specify the maximum load for theelevators in a new building. Each elevator has a mass 490 kg when empty and maximumacceleration 2.24 m/s2. The elevator cables can withstand a maximum tension of 19.5 kN beforebreaking. For safety, you need to ensure that the tension never exceeds two-thirds of that value.What is the maximum load that the elevator can safely carry? How many70-kg people is that?Briefly but clearly explain the reasoning for your choice of the sign of the acceleration.

A 90 degrees angle on a 1/2 inch water pvc pipe. determine the force on the angled pipe if the water prusser is 30kpa.

2) The form is used to cast a concrete wall having a width of 5 m. determine the equivalent resultant force the wet concrete exerts on the form AB if the pressure distribution due to the concrete can be approximated as shown. Specify the location of the resultant force, measured from point B. p = (422) kPa- 8 kPa B 4 m

As shown in Figure 2.3, the total height of the liquid in the canal in Part (a) is now increased to 3R. Determine the minimum force F applied at B to prevent the gate ABC from opening (i.e. turning anticlockwise about the hinge A). Neglect the weight of the gate and friction in the hinge.
