A P KN Refer to the figure. d₁ 0.9 m Force P is 60 kN and each force Q is 125 kN. Q KN B Add your answer Integer, decimal, or E notation allowed Q KN The diameter d₁ = 30 mm and diameter d₂ = 50 mm. d₂ 1.2 m What is the normal stress in rod BC in MPa? Round to the nearest integer and enter the magnitude only. C

Solve both question.... It's objective type questions so as per bartlybe's guidelines you need solve both question.

A solenoid similar to the figure below, has a core made of cast steel (refer to the figure on the next slide). It has a cross-sectional area of 4cm2  and a mean length of 20cm. The coil has 100turns, and the coil current is 3.2A. Find the following: a)magnetomotive force, mmf b)magnetic field intensity, H c)flux density, B

A ring of ferromagnetic material has a rectangular section. The inner diameter is 15 cm.The outer diameter is 24 cm. And the thickness is 5 cm. There is a coil of 500 turns wound onthe ring. When the coil has a current of 10 A, the flux in the core is 0.0007 Wb. Theaverage length of the ring is Ln=0.66m Determine:a) The magnetomotive force.b) The intensity of the magnetic field and the flux density.c) Reluctance, permeability and relative permeability.
