    Acceleration of a car when given torque and mass

    I have the understand torque is the mesument of power around a pivot point... I am not entirly sure, this is proberbly why i am haveing trouble with the question..

    Acceleration of a car when given torque and mass

    Newtons of force... Would that be the mass...? soo 1200kg or 11767.98 N. Is this what you mean?

    Acceleration of a car when given torque and mass

    A car has a mass of 1200kg and delivers a total of 2300Nm of torque. Tyre radius of 0.306m. What is the acceleration of the car in m/s^2? What is the speed of the car if it has accelerated for 11 seconds? (determained in first question), I have looked at a few and still a bit stuck...

    Power Loss over 1st Light Bulb in DC Circuit w/10Ω, 12Ω, 10Ω & 12V

    A DC circuit has resistances of 10Ω, 12Ω, and 10Ω respectively. Also has 2 light bulbs with identical tungsten (resistivity = 5.6* 10^-8) filament bulbs with filament thickness of 12um and length of 1.2cm. The source is a 12V. what is the power loss over the first light bulb? I am not...

    What is the mass of the counterweight in a two-leaf bascule bridge?

    I think what the question is asking is at what slope (degree) would the truck start moving backwards? So I assume that some sort of friction equation would solve this. All the information we were given is what I posted befor... I know how to find it if the mass was given but it is not given..

    What is the mass of the counterweight in a two-leaf bascule bridge?

    Thank you soo much IOU :D I do have just one more question which relates to the last one... The bridge from problem 3 needs to draw up the leaves to let a ship through. The leaves are being lifted when someone notices a truck has broken down on one leaf and cannot be moved. It takes some time...

    What is the mass of the counterweight in a two-leaf bascule bridge?

    Would I be right to say... (f1*L)+(F2*L2)+(F3*L3)=0 (0*25)+(10,000*12.5)+(x * -1)=0 (0)+(125,000)+(x * -1)=0 (125,000)= -(x * -1) 125,000/1 = -x * 1 /1 125,000 = -x

    What is the mass of the counterweight in a two-leaf bascule bridge?

    Modern day draw bridges are also known as bascule bridges. These can have one or two sides (one is called a leaf) that are drawn up from each end of the bridge so that boats can pass through water channels. In some designs, each side of the bascule bridge is held in place by a counter-weight...
