Example 3

The linkage ABDE

moves

in the

vertical plane. Knowing

that in the

position

shown

crank SB has a constant angular velocity

co~

of 20

md/s

counterclock

wise,

determine

the angular veloci ties

and

angular accelerations of

the

con

necting

nd

EL)

and of the crank VS.

When the forward

speed

of the truck shown

was

30 1k/s. the brakes

were

suddenly applied, causing all four whels to

stop

rotating. It

was

observed

that the

truck

skidded to

rest

in

20

IL

Determine

the

magnitude

of

the

normal reaction tad of

the

friction force at each wheel as

the truck

skidded

to rest.

A

completely

filed

barrel and its contents have

a

cowbined weight

of

200

lb.

A cylinder C is

connected

to th& barrel

at

a

height

h

= 22

in. as

shown. Knowing

/4 =

0.40 arid

p1 = 0.35, determine the maximum

weight

of

C

so

the baste

will

not tip.
