The particle has a mass of 0.7 kgkg and is confined to move along the smooth horizontal slot due to the rotation of the arm OAOA. Assume the particle contacts only one side of the slot at any instant. The arm has an angular acceleration of θ¨θ¨ = 3 rad/s2rad/s2 when θ˙θ˙ = 2 rad/srad/s at θθ = 30∘∘. Determine the magnitude of the force of the rod on the particle when θ = 30∘. Determine the magnitude of the normal force of the slot on the particle when θ= 30∘

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
