PROBLEM 2 The elements of a floor jack are shown in the figure. If the hydraulic cylinder AB is designed to support a maximum compressive force of 37 kN, determine at this condition the load L (in kN) and the force (in kN) in link EF. Also, calculate the corresponding pin reaction (in kN) at C. Draw the correct FBD's of the hydraulic cylinder AB, link EF and platform DF. Also, draw the combined FBD of the platform DF and member BCD. Note that figure CDFE if traced is a parallelogram. Also, members BCD and EF are connected to the base of the jack by pins at C and E, respectively. Disregard friction between the contacting faces of members BCD and EF.

Figure 14.32 Measurement of fluid speed on Bernoulli’s principle. (a) A manometer is connected to two tubes close together and small enough not to disturb the flow. Tube 1 is open at the end facing the flow. A dead spot having zero speed is created there. Tube 2 has an opening on the side, so the fluid has a speed v across; thus, pressure there drops. The difference in pressure at the manometer is 12v22 , so h is proportional to . 12v22 (b) This type of velocity measuring device is a Prandtl tube, also known as a pitot tube.
