From the given link, ab sine 45 degree is equal to e.
00:22
F.
00:25
Ab sign 45 degree is equal to 15.
00:37
Ab is equal to 21 .21 inch.
00:48
Now write velocity equation velocity equation for motion for motion of points b point b so this is v b is equal to v b is equal to v d this is vb -e plus vb -d -dez plus ve.
02:03
Here b -dase is point indicating with the bar -de at the given instant.
02:13
V -b is absolute velocity.
02:16
V -b -d -e is velocity of point b -dess with respect to point e perpendicular to bar -de -e.
02:24
V -b -dance is sliding velocity of point b -d -a -long -d -d and v is absolute velocity of point e perpendicular to ef in the direction of angular velocity of bar ef.
02:39
Now draw, draw velocity polygon city polygon for point point b.
03:10
E is equal to b e multiply by omega e d now velocity polygon is drawn like this ve this is vee this is vee b dash this is v b b dash e and this is v b b and this is v b 45 degree so now omega ed angular velocity of link ed so from our equation v b dash e is equal to 20 value of b is 20 multiply by omega ed this is 10 so we v -e -e is equal to 200 inch per second.
04:45
Now absolute velocity of point e, point e is ve is equal to ef multiply omega ef.
05:16
This is equal to 15 inch multiply by 15 radian per second.
05:29
On solving this, ve is equal to 225 inch per second.
05:38
Now point a is consider velocity polygon...
