Calculate the force acting on the gate

The spring clamp of Fig. block Fagainst the floor. The force in the spring is F = k(e – lo), where e is the present length of the spring, lo = 3 in. is the unstretched length of the spring, and k = 240 lb/ft is the spring constant. Determine all forces acting on mem- ber ÁBC of the spring clamp and the force exerted by the spring clamp on the block E. is used to hold the 8 in. D E 8 in. 6 in -6 in.- 6 in.

The brake system in most cars makes use of a hydraulic system. This system consists of a fluid filled tube connected at each end to a piston. Assume that the piston attached to the brake pedal has a cross sectional area of 0.6 cm2 and the piston attached to the brake pad has a cross section area of 2.4 cm2. Determine the force at the brake pad, if you apply a force of 10 N to the piston attached to the brake pedal. Please show the formulae, the calculations, all the steps.

2) The form is used to cast a concrete wall having a width of 5 m. determine the equivalent resultant force the wet concrete exerts on the form AB if the pressure distribution due to the concrete can be approximated as shown. Specify the location of the resultant force, measured from point B. p = (422) kPa- 8 kPa B 4 m
