    Cantilever beam with curved beam on the end.

    struggling to find info on this so figgured i'd as. For two beams attached to each other, one a straight catilever and the second a 90 degree bent beam attached to the end of the cantilever (shown in attached picture). To calculate the deflection of the beam at the load applied, given the...

    Archived DC motor in series, finding the speed

    Homework Statement when running at its rated load, a 40kW series motor takes 74A and 550V. The rated speed is 750 rev/min. the armature and field resistances are 0.35 Ω and 0.15 Ω respectivly. when the load torque is doubled the rated value, the current is 110A. dertermin the moror speed and...

    Car impact at 90 degrees to each other (conservation of momentum)

    Oh snap. so: 1000 x 10 = 2400 x cos(25) x v' 10000 / ( 2400 x cos (25) ) = v' v' =4.6ms^-1 and then reversing this for the horizontal 1400v = 2400 x sin(25) x 4.6 v = (2400 x sin(25) x 4.6) / 1400 v= 3.3ms^-1

    Car impact at 90 degrees to each other (conservation of momentum)

    Homework Statement Two cars collide at right angle in the intersection of two icy roads. Car A has a mass of 1000 kg and car B 1400 kg. The cars become entangled and moved off together with a common velocity v’ in the direction indicated in figure QB4. If car A was traveling 10 m/s at the...
