Consider a hydraulic jack being used in a car repair shop, as in the figure. The pistons have an area of A 1 = 0.8 cm 2 and A 2 = 0.04 m2. Hydraulic oil with a specific gravity of 0.870 is pumped in as the small piston on the left side is pushed up and down, slowly raising the larger piston on the right side. A car that weighs 17000 N is to be jacked up. a) At the beginning, when both pistons are at the same elevation ( h = 0), calculate the force F 1 in newtons required to hold the weight of the car. %3D b) Repeat the calculation after the car has been lifted two meters ( h = 2 m).

Industry Print Exercise 23-2 Refer to print PR 23-2. The sequence of operations for this print is given below. Answer the questions following the sequence of operations. Sequence of Operations descends at a controlled rate, slowly compacting the explosive charge to avoid detonation due to a sudden Description: This is a system to control a 90-ton hydraulic, explosive-compaction press. The press ram shock. 1. The cycle is started by energizing solenoid A, which shifts control valve 3 and supplies pressure to the head end of the hydraulic cylinder (7). This operates the ram. 2. The cylinder (7) extends at a slow rate controlled by the fluid in the rod end of the cylinder, which is vented through the flow control valve (5). the 1. When de-energizes solenoid A and energizes solenoid B. This shifts control valve 3 to retract the cylinder (7). de rol valve 5 has an integral check valve that permits the free flow of fluid in the opposite direction, causing the cylinder (7) to rapidly retra…

A lineshaft runs at 380 rpm. A 18 inches pulley on the same shaft is belt connected to a 12 inches pulley on the countershaft. From a 15 inches pulley on the countershaft, motion is transmitted to the machine. Compute the required diameter (in inches) of the pulley of the machine to give a spindle speed of 660 rpm.
A step by step answer please

Gentlemen, please help to solve a,b,c as I faced confusing questions about screw jack. Conditions are: screw jack is lifting 3.2 tonnes, screw pitch is 12 mm, diameter of the screw is 5 mm. Coefficient of friction was not given but I think we will need it for total force calculation, lets take it 0.2. a) Calculate horizontal component to move the load - what is ment here by horizontal component? b) Calculate vertical component to move the load - what is ment here by vertical component? c) Total force needed to move the load with a lever of 0.82m d) Velocity ratio (VR=distance by effort/distance by load) Distance by effort (lever)=2 x 3.14 x 0.82 = 5.15m Distance by load = pitch= 12mm= 0.012 m VR=5.15/0.012= approx 429. e) Calculate efficiency. For this we need to have MA (mechanical advantage). It can be calculated when we know total force. Efficiency=Load (3200 x 9.8) / effort
