The I-section has the dimensions (in mm) shown in the figure. Calculate the second moment of area about the X-X axis when D = 285 mm and W = 136 mm. Input your answer as a value only in (centimetre) 4 to zero decimal place. W mm 15 mm Y I ---X Y 10 mm - X D mm 15 mm

can you provide an answer easie to read. the answer is put into sentences like fcv=mgcos 6

Hello. Can you please help answer the question shown in the photo? It is a 3-part question which I have attempted many times. I was able to calculate the correct answer for part 2, but part 1 and part 3 still says I am incorrect. Please show how to properly solve the problem. The topic is heat transfer. Thank you.

i) Find the property that provides the change in size of the material, if the material is subjected to temperature change and explain that property with unit. ii) Water of 1.6 liters is heated to a maximum temperature of 116 °C from room temperature to prepare Arabic coffee for a family using the following data. -- (2.5 Marks) - Heat energy of 623 kJ is supplied to the water - Specific heat capacity of water is 4.2 kJ/kg K - Density of water as 1000.5 kg/m3 Determine the room temperature. a) Mass of water (in kg) b) Room temperature (in °C

Please answer with units every proceedure what is the volume (ft^3) occupied by water if has a weight of 283 lbf

i need the answer quickly

Whats the correct answer for this please ?

1. An ingot of mass 1,148 kg contains copper, tin, and lead in the ratio 9:4:1. Calculate the value of the ingot if the price per tonne of the metals is copper: $ 1,250, lead: $ 680, tin: $ 8,600.

A gas filled in a piston-cylinder arrangement as shown in Figure 1 has a volume of 0.09 m³ at its initial equilibrium state. The gas is slowly heated through the bottom of the cylinder that allowed for the gas to expand at constant-pressure of 2095 kPa to a volume of 1.23 m°. The change in internal energy of the gas is 0.24 kJ. Ignoring the friction between the piston and the cylinder and assuming the atmospheric pressure any value from 90 to 110 kPa, of (a) Calculate the mass of the piston if the area of the piston is 0.047 m2 (b) For the gas as a system, evaluate work and heat transfer, each in kJ (c) For the piston as a system, evaluate work and change in potential energy, each in kJ Piston Gas
