Project Design a windshield wiper mechanism for a truck as shown in the figure below. A force F1 is applied to lever 1 by an adjacent link. The reaction force, F2, on lever 2 is transmitted to another link. Let the distance, d, between elements is 20.0 mm. You are required to design the complete system. Submit full design calculation, assembly drawing and working drawings.

00:01 So in this question we have what is the characteristics of a liver.

00:05 So river is what? liver is a simple machine.

00:23 It is a rigid straight or bent rod which is capable of turning around an axis.

01:16 These are the characteristics of a river.

01:20 Okay.

01:22 Now for the second part we have different types of levers and the character etc.

01:28 So in the form of a table we can have the answer so this is the answer actually.

01:37 So you can see here for different types of objects first of all we have objected scissors so uses what to cut something.

01:46 The location of the outcome of a scissors is what screw joining the metal blades.

01:51 We have two metal blades that's two joining the metal grid is the position of the falcon.

01:56 Resistance here is the resistance because resistance is the thing which we need to cut here.

02:03 So this is a resistance.

02:04 What we put there for? finger holes in the hand of the scissors.

02:10 And this is a type of liver is fast -class liver.

02:12 So here we are considering spoon when you are using it to open a lid.

02:18 So to open a lid, to open a lid.

02:21 So what is the position of the position of the spoon? the fulcrum, the point tattoos the screw, touches the can or the bottle.

02:28 Again, it is resistance, no load actually, no weight is actually here.

02:34 We are not overcoming any weight or we are not lifting any weight with the spoon.

02:40 We are actually opening a lid...
