Which equation represents Grubler’s equation? (where “F”represents Degrees of freedom, n represents number of links, l represents Number of lower pairs, h represents Number of higher pairs)

Correct Answer: F = 3(n-1)-2l-h
F = 3(n-1)-2l-h represents Grubler’s equation. (where “F”represents Degrees of freedom, n represents number of links, l represents Number of lower pairs, h represents Number of higher pairs). This equation is used to determine the Degree of freedom of a system.

The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where $$l$$ = Number of links and j = Number of binary joints)

A palnar mechanism has 8 links and 10 rotary joints. The number of degrees of freedom of the mechanism, using Grubler’s criterion, is

The Kutzbach criterion for determining the number of degrees of freedom (n) is (where $$l$$ = number of links, j = number of joints and h = number of higher pairs)

Match the items in columns I and II Column I Column II P. Higher Kinematic Pair 1. Grubler’s Equation Q. Lower Kinemation Pair 2. Line contact R. Quick Return Mechanism 3. Euler’s Equation S. Mobility of a Linkage 4. Planar 5. Shaper 6. Surface contact

The minimum number of links in a single degree-of-freedom planar mechanism with both higher and lower kinematic pairs is

The Grubler’s criterion for determining the degrees of freedom (n) of a mechanism having plane motion is

Which of the following best explain why the lower course of a river is sometimes choked with sediments?
1. The valley of a river is widest in its lower course.
2. The velocity of a river in its lower course is low.
3. The delta sometimes develops in a river's lower course.
4. Much of the river water is drawn for irrigation in the lower course.

When supported on three points, out of 12 degrees of freedom the number of degrees of freedom arrested in a body is

If a higher priority process arrives and wants service, the memory manager can swap out the lower priority process to execute the higher priority process. When the higher priority process finishes, the lower priority process is swapped back in and continues execution. This variant of swapping is sometimes called?

The relation l = 2/3(j+2) apply to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to
