Answer:

Figure (4)

Explanation:

In this case 4 free body diagrams are shown. In Figure (1), there is no normal force acting on the object. It will accelerate in downwards direction.

In figure (2), the box is balanced. All forces cancel out each other.

In figure (3), the box is not balanced. The horizontal forces cancel out each other while the downward force is greater than the greater than upward force. The object will accelerate in downward direction.

In figure (4), no normal force is acting. In this case, the force towards right is more than the force towards left. So, the object will move towards right.

Hence, the correct option is (c) " figure (4) only".

Assume a beam with stirrups inclined at 60o angle with respect to the longitudinal steel resisting cracks developing at 45o angl
arlik [135]

Answer:

Shear resistance of a inclined stirrup is given by  

 Vᵇ = Asb(0.95*Fy)(cos α - sin α*cotβ) ((d-d')/sᵇ)

Explanation:

The shear resistance is checked in accordance with BS8110: Part 1, section 3.5.5. Shear resistance of a inclined stirrup is given by  

 Vᵇ = Asb(0.95*Fy)(cos α - sin α*cotβ) ((d-d')/sᵇ)

where,

 Vᵇ=design shear resistance of inclined bars

Asb=cros-sectional area of the inclined bars

Fy=characteristics strength of the stirrups

α=angle between the inclined bars and the axis of the beam

β=angle between the compression strut of inclined bars and the axis of the beam

sᵇ=spacing of the inclined bars

d= effective depth   and d'=effective depth minus cover to reinforcement

The shear stress is given by    

v=V/bd  

 where V is the shear force due to ultimate loads. If v is shear stress

Juan and Kuri are on a carousel. Juan is closer to the center of the carousel than Kuri. Which statement describes their tangent
Licemer1 [7]

Answer:

Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.

Explanation:

Since Juan is closer to the center and Kuri is away from the center so we can say that Juan will move smaller distance in one complete revolution

As we know that the distance moved in one revolution is given as

d = 2\pi r

also the time period of revolution for both will remain same as they move with the time period of carousel

Now we can say that the speed is given as

v = \frac{2\pi r}{T}

so Juan will have less tangential speed. so correct answer will be

Juan and Kuri complete one revolution in the same time, but Juan travels a shorter distance and has a lower speed.
