The torque required to drive a 40 mm diameter power screw having double square threads with a pitch of 6 mm is 1.0 kn-m. the friction for the thread is 0.10. is the condition self-locking? show your calculation.

This is self locking.

Explanation:

Given that

Diameter d= 40 mm

Pitch (P)= 6 mm

Torque T= 1 KN.m

Friction(μ) = 0.1

Thread is double square.

Condition for self locking

L= n x P

N= number of start

Here given that double start so n=2

L=2 x 6 = 12 mm

           (μ = 0.1)

So from we can that this is self locking.

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
