A differential wheel and axle is used to lift a box of mass 400kg. The larger and Smaller radii of the beam
are 40cm and 30cm respectively. The length of the Crank
arm is 50cm. If the efficiency of the machine is 80%
Determine the motive force required to lift the load-

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
