## Applied Mechanics and Graphic Statics The time period of a simple pendulum depends on (i) Mass of suspended particle (ii) Length of the pendulum (iii) Acceleration due to gravity

Both (i) and (iii)
Both (ii) and (iii)
Only (i)
All are correct

y = c sin x/c
y = c sinh x/c
y = c cosh x/c
y = c tan x/c

## Applied Mechanics and Graphic Statics Three forces which act on a rigid body to keep it in equilibrium. The forces must be coplanar and

Parallel
None of these
Concurrent parallel

## Applied Mechanics and Graphic Statics The resultant of the forces acting on a body will be zero if the body

Moves along a curved path
Moves with variable velocity in a straight line
Rotates
Does not move at all

## Applied Mechanics and Graphic Statics A square hole is punched out of a circular lamina, the diagonal of the square being the radius of the circle. If ‘r’ is the radius of the circle, the C.G. of the remainder from the corner of the square on the circumference will be

[r (π + 0.25)]/(π + 0.5)
[r (π + 0.25)]/(π - 0.5)
[r (π - 0.25)]/(π - 0.5)
[r (π - 0.5)]/(π + 0.25)
