Question
Identify the order of the two levers shown below. This task gives opportunities to provide evidence toward Assessment Criterion P13. This crate, holding 40 bricks, each of mass 1.3kg, is placed on a hydraulic lifting beam as shown. State the order of the lever used here. Calculate the effort required to lift the load. Calculate the mechanical advantage for this system. Calculate the velocity ratio for the system shown below.Explanation / Answer
7. a) first order (since F is between L and E) b) second order (since L is between F and E) 8. a) third order (since E is between L and F) b) Effort (E) is provided by hydraulic ram while the weight provide the load (L). equating the torque about the pivot (Fulcrum), E*1 = 40*1.3*9.8*(5+1) = =>E= 3057.6 N c) mechanical advantage is that the hydraulic ram needs to go up little distance for lifting the load to a large distance. d)let vE = velocity of Effort. vL = velocity of Load. since the angular velocity is same. thus vE/1 = vL/6 =>vE/vL = 1/6
