Place the lamb in the oven. For cooking time allow 30 minutes per 500g. Cover the lamb with foil after 20 minutes to avoid it becoming too brown, then uncover for the final 20 minutes of cooking. Top up the water a little as the lamb cooks to avoid the lamb drying out.

They are fundamentally different concepts. Horsepower is a unit of power which is the amount of work (W) which can be performed in a unit of time (t). Torque (tau) is a measure of force (F) applied across a moment arm (r). You can think of horsepower as literally the amount of power that a horse could perform. You can think of torque as the amount of twisting force on a crankshaft. In terms of real world results, torque is that neck-snapping feeling when you take off.
