  We study the origin of the supersymmetry breaking induced by the mediation of
gravity and the radion multiplet from the hidden to the visible brane in the
context of the N=2, D=5 supergravity compactified on S_1/Z_2 orbifolds. The
soft supersymmetry breaking terms for scalar masses, trilinear scalar couplings
and gaugino masses are calculated to leading order in the five dimensional
Newton's constant k_5^2 and the gravitino mass m_{3/2}. These are finite and
non-vanishing, with the scalar soft masses be non-tachyonic, and are all
expressed in terms of the gravitino mass and the length scale R of the fifth
dimension. The soft supersymmetry breaking parameters are thus correlated and
the phenomenological implications are discussed.
