The force of magnitude f acts along the edge of the triangular plate. determine the moment of f about point o. find the general result and then evaluate your answer if f = 260 n, b = 580 mm, and h = 370 mm. the moment is positive if counterclockwise, negative if clockwise.

The moment is 81.102 k N-m in clockwise.

Explanation:

Given that,

Force = 260 N

Side = 580 mm

Distance h = 370 mm

According to figure,

Position of each point

We need to calculate the position vector of AB

We need to calculate the unit vector along AB

We need to calculate the force acting along the edge

We need to calculate the net moment

Put the value into the formula

Put the value into the formula

Negative sign shows the moment is in clockwise.

Hence, The moment is 81.102 k N-m in clockwise.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
