Design a tension member and slip-critical splice to carry a factored load of 500 kips. Please use a wide-flange section for the
Svetlanka [38]

Answer:

Kindly check the explanation section.

Explanation:

For the design we are asked for in this question/problem there is the need for us to calculate or determine the strength in fracture and that of the yield. Also, we need to calculate for the block shear strength.

From the question, we have that the factored load = 500kips. Also, note that the tension splice must not slip.

Also, the shear force are resisted by friction, that is to say shear resistance = 1.13 × Tb × Ns.

Assuming our db = 3/4 inches, then the slip critical resistance to shear service load = 18ksi(refer to AISC manual for the table).

If db = 7/8 inches, then the shear force resistance for n bolt = 10.2kips, n > 49.6.

The yielding strength = 0.9 × Aj × Fhb= 736 kips > 500

The fracture strength = .75 × Ah × Fhb = 309 kips.

The bearing strength of 7/8 inches bolt at the edge hole and other holes = 46 kips and 102 kips.

Two people push on a boulder to try to move it. The mass of the boulder is 825 kg. One person pushes north with a force of 64 N.
stira [4]

Answer:

0.09 m/s²

Explanation:

Acceleration: This can be defined as the rate of change of velocity.

The S.I unit of acceleration is m/s².

From the question, expression for acceleration is given as

F' = ma  

Using Pythagoras Theory,

√(F₁²+F₂²) = ma................... Equation 1

Where F₁ = Force of the First person on the boulder, F₂ = Force of the Second person on the boulder, F' = resultant force acting on the boulder, m = mass of the boulder, a = acceleration of the boulder.

make a the subject of the equation

a = √(F₁²+F₂²) /m................ Equation 2

Given: m = 825 kg, F₁ = 64 N, F₂ = 38 N,

Substitute into equation 2

a = [√(64²+38²)]/825

a = {√(5540)}/825

a = 74.43/825

a = 0.09 m/s²

You are part of a mission to Mars and have been assigned the task of designing balloons for the purpose of carrying scientific i
melomori [17]

Answer:

<em>The radius of the balloon is R=  0.974 m</em>

Explanation:

Atmospheric density on the surface of mars ρ  = 0.0154 kg/m³

Mass  density of balloon σ  5 gm/m² = 0.005 kg/m²

Total mass of balloon M  = density of balloon* surface area

The balloon is considered as sphere

Surface area of sphere is given by  4π R²

Mass of balloon is M =σ *4πR²

                      M= (0.005 kg/m²)*(4π R²)

Volume of balloon is given by  \frac{4}{3} πR³

Density of atmosphere of mass is given by  

   ρ = Mass of balloon/volume of  balloon

       =(0.005 kg/m²)*(4π R²)/  \frac{4}{3} πR³

Re arranging R

R =  \frac{3*0.005 kg/m²}{ 0.0154 kg/m³}

   R = 0.974 m

<em>The radius of the balloon is R=  0.974 m</em>

What is true when an object is moved farther from a plane mirror?
musickatia [10]

Answer:

For a plane mirror, the image distance equals the object distance, so the image distance will increase as the object distance increases

The height of the image stays the same and the image distance increases.)

Explanation:

For plane mirrors, the object distance (is equal to the image distance. That is the image is the same distance behind the mirror as the object is in front of the mirror. If you stand a distance of 2 meters from a plane mirror, you must look at a location 2 meters behind the mirror in order to view your image
